Imam, Ali son of Musa al-Rida (A.S.) was born in the reign of Abu-Ja'far Mansoor, 
and survived the regimes of Abbasid caliphs Mahdi, Hadi, Rasheed, Amin, and 
Ma'moon. During it, the major Islamic schools of thought were set up.
The religious scholars and learned men found refuge in Imam Rida (A.S.) who 
argued with commentators, discussed with philosophy students and masters, 
refuted the claims and suspicions cast by the atheists and exaggerators, issued 
guidelines to the legal jurists, and stated the basis of shari'a and principles 
of monotheism.
The legal jurisprudents, wisemen, sufis, preachers, infidels and ghulat attested 
to his abunant knowledge, the strength of his arguments, and his supremacy in 
all the debates that were held between him and the foes of Islam. Mohammad, son 
of las Yaqtini, admits that:
"When people differed about Abul-Hassan al-Rida (A.S.), all the answers he had 
given to questions posed to him were collected. They totaled fifteen thousand."
The Imam's knowledge and sciences were the inheritance of the prophethood and 
Allah's gift to him and, in which, knowledge were discovered and facts were 
explained for him. The author of 'I'lam Wara bin a'lam Huda' (Acquainting People 
with the Leaders of Guidance) quoted Aba Salt Harawi as saying: "I have never 
seen a man more knowledgeable than Ali, son of Musa al-Rida (A.S.), nor has any 
scholar see him without giving a testimony like mine. In his assembly, Ma'moon 
gathered before him a number of religious scholars, jurists of shari'a, and 
preachers. In the argument that took place, he defeated them all. 
There remained no one who did not admit al-Rida's outstanding virtues, and his 
own helplessness. I heard him saying: 'I used to sit with them at Rawdah. The 
religious scholars of Madinah were numerous, but, when one of them failed to 
find a solution to any question, all of them would refer to me. They would send 
me the questions and I would answer them.'
Abul-Salt then says: 'Mohammad, son of Ishaq, son of Musa, son of Ja'far (A.S.), 
used to say to his sons: 'This is your brother Ali, son of Musa, the prominent 
scholar of the Prophet's descendants. Ask him about anything related to the 
faith, and learn well what he says to you."
Social Conditions under Abbasid Rule
Life inside the Abbasid palaces has been perfectly described by historians, 
biographers and poets. It was a grave tribulation for the Muslim ummah. Money 
was wasted on the purchase of slaves, building palaces, buying jewelry and 
rewarding the praising poets. Supporters were bought, and festivals and parties 
along with their supporters and sympathizers. Those few who were spared lived in 
permanent danger of death or imprisonment, with their property confiscated.
Now, let us look at some history books and see how the historians describe those 
times.
Historians wrote a lot about Rasheed's extravagance, his squandering of the 
umma's wealth, and his engagement in entertainment and frolic. We quote some 
narratives here:
In his book 'Tarikh Khulafa'' (History of the Caliphs) Suyooti says: "Rasheed 
once gave Sufyan, son of Uyayna, 100,000, rewarded Ishaq Moosili with 200,000, 
and rewarded Marwan, son of Abu Hafsa - With 5,000 dinars for a poem the latter 
recited in praise of him."
Sayooti adds that, "He was engaged in pleasure-chasing and singing."
Sayooti also says: "When Rasheed took over the 'caliphate' after the demise of 
his father, he took a fancy to one of his father's female slaves, He tried to 
seduce her. She rejected him saying, 'I am unfit for you, your father slept with 
me.' But, Rasheed's desire for her increased. He sent for Abu-Yusuf ( the, then, 
chief of judges) and asked him: 'Is there anything you can do about this?' 'O 
Caliph of the Faithful! Every time a slave claims something do you believe her? 
Do not believe her. She is not trustworthy!"
Ibn Mubarak, commenting on this episode, said: "I do not know what is more 
surprising to me: This, that who has shed Muslim blood and plundered their 
wealth and property, should refrain from violating the advances of the Commander 
of the Faithful, or this, that, the legal jurisprudent and chief justice on the 
earth should say (to Rasheed): 'Violate the sanctity of your father, attain your 
desire, and I will take all responsibility for this act!'
He adds: "After his death, Rasheed left behind one hundred million dinars and 
furniture, jewelry and animals to the value of one hundred million and 
twenty-five thousand dinars."
Political Conditions in which the Imam Rida (A.S.) 
lived
 
Imam al-Rida (A.S.) lived in the same critical period as his father and when his 
father was martyred, he became the Imam. But, the caliph, Rasheed, did not 
confront him, instead, he (Rasheed) said to Khalid, son of Yahya Barmaki who 
warned him against Imam Rida (A.S.): "What we have done to his father is quite 
enough for us."
But, nevertheless, Imam al-Rida (A.S.) could not stay out of the reach of the 
Abbasids. He was in the heart of the struggle that was going on between the 
Abbasids and the descendants of Imam Ali (A.S.).
The deterioration of the political conditions of the rulers had a very bad 
harmful effect on the people, both common, and their leaders, notabales and 
scholars. As a result, there emerged a voice, strong and loud, in favour of 
Ahlul-Bait (A.S.). It was the chiefs of Ahlul-Bait, like Imam al- Sadiq (A.S.), 
Imam al-Kadhim (A.S.) and al-Rida (A.S.), who were the hub around which people 
rallied, finding in them the hope of the umma.
Synpathy for Ahlul-Bait (A.S.) mounted and reached its climax during the 
leadership of Rida (A.S.). 
Even some senior officials and military officers expressed their sympathy with 
Ahlul-Bait (A.S.). While the Abbasid state was being thrown into great confusion 
and internal struggle between Amin and his brother Ma'moon, Imam al-Rida (A.S.) 
won more followers and admirers as being the leading personality from Ahlul-Bait 
(A.S.). Eyes were glued to him and hearts hovered around him.
Revolts and Uprisings
After Ma'moon overcame his brother Amin and took power from him, he faced 
continuous revolutions led by the Alawites, due to the Abbasid policy and 
conditions of pursuit and oppression which caused them to carry out armed 
movements and revolutions in order to defend the truth by force. Ma'moon held 
the same view, about the Imams of Ahlul-Bait (A.S.), that his forefathers held. 
He led a bitter struggle with his brother Amin, while he was besieged by a 
number of Alawite revolts and uprisings.
Unlike his forefathers, Amin did not resort to violence against Imam al-Rida (A.S.). 
He ended up favouring one political choice; to make a truce with the descendants 
of Ali, son of Abu-Talib (A.S.), acknowledging their right to rule. He did so in 
order to convince people of his moderation, 
win over followers and relieve the umma of the atrocities of the previous 
Abbasid rulers. It, was, also, a good way of combatting the rising Alawite 
opposition which was strengthened, greatly, by the internal disputes within the 
Abbasid ranks; the terrorism, bloodshed, squandering of the umma's riches, 
misrule, and the lapse into insecurity.
Ma'moon, thus, invented a political plan to contain Imam al-Rida (A.S.). He 
appointed him his heir apparent, as he was the sole Imam from the Prophet (peace 
be upon him), and the leading, unparalleled leader of his time.
Post of Heir Apparent
The best, and probably the only possible way out of the political crisis 
besetting Ma'moom lay in persuading Imam Rida (A.S.) to accept the idea of being 
his successor. By so doing, Ma'moon thought he could win over the opposition to 
his side and put both the Abbasid and Alawites under his control.
Imam al-Rida (A.S.) realized the dimensions of this political scheme of Ma'moon 
and that, thus, he (A.S.), many times, refused what Ma'moon exposed for him. 
But, later on, he accepted the post after being threatened, by Ma'moon, to be 
killed.
Imam al-Rida (A.S.) agreed, under coercion, to accept the post, and so that he 
would not share the rulers' guilt over their misuse of power, he set his own 
conditions. It was a symbolic ceremony. Nothing real was to come out of it.
But, it was enough for Ma'moon, who ordered the announcement of the great news 
throughout the Muslim homeland and called people to give pledge of allegiance to 
the Imam.
The ceremony of giving the pledge of allegiance to Imam al-Rida (A.S.) was 
conducted before a multitude of people, the size of which was unprecedented in 
Islam. After the ceremony, Ma'moon asked Imam al-Rida (A.S.) to deliver a speech 
to the people.
Imam al-Rida (A.S.) rose up, and in a few, eloquent words, he explained his 
position toward the existing authorities, and showed that he could not bridge 
the gap between himself and the ruler. He said, after praising Allah: 
"We have a right over you, as we are the progeny of the Messenger of Allah (pbuh&hh). 
As he is your honour your obligation towards us, we will certainly do the same 
for you."
This address, of the Imam (A.S.) is the testimony of his mistrust for the future 
of the covenant. In it, he alludes to his doubts by saying, "Should you honour 
your obligation towards us, we will certainly do the same for you."
Sheikh Mufid quotes Mada'ini as having said: "When Imam al-Rida (A.S.) took his 
seat at the celebration made to confer the post of "heir apparent" on him by 
Ma'moon, speakers and poets took turns praising him and showing their happiness 
on the occasion. Standards fluttered overhead. A close companion of Imam al-Rida 
(A.S.), who was present, related: 'I was sitting beside him on that day. He 
looked at me. I was very happy at what had taken place. He beckoned to me to 
draw near him and I did. 'Do not bother with this matter, 'he said under his 
breath lest someone hear us, 'Do not rejoice at it. It is something that will 
never be realized.'"
The caliph, Ma'moon was not that person who refrains himself from the world's 
pleasures, including power. He killed his brother, Amin, for the sake of power 
and killed those who served him or those who served his father, Rasheed, such as 
Tahir bin Hussein, Fadl bin Sahl, and others who 
participated in executing the plans of Ma'moon in establishing his authority.
It was only natural that Imam al-Rida (A.S.) would meet the same fate because he 
was more dangerous, in the eyes of Ma'moon and his inner circle, than any other 
man at that time. Added to that was the infighting, the false reports and the 
attempts to distort the image of Imam al-Rida(A.S.) in the Abbasid palace.
History tells us that Ma'moon put poison into some fruit (pomegranates) which 
was presented to Imam al-Rida (A.S.), and, thus, he martyred the Imam (A.S.).
Ma'moon felt the situation would be very grave for himself, and the reaction of 
the descendants of Ali (A.S.), and the masses of the umma, would be very violent 
of he were to be accused of murdering the Imam (A.S.).
Historians have it that people immediately pointed an accusing finger at Ma'moon. 
They blamed him, directly, as the murderer of the son of the Prophet of Allah (pbuh&hh). 
People buzzed with the news of the Imam's martyrdom, particularly around the 
house where the body of the Imam(A.S.) was laid. 
Fearing a massive reaction on the part of the people, for it was a good 
opportunity that could be seized to stir up people's feelings, Ma'moon asked 
Mohammad, son of Ja'far, the paternal uncle of Imam al-Rida (A.S.) to go that 
the funeral of the Imam (A.S.) would be postponed.
Thus, Imam al-Rida (A.S.) departed for ever, reciting this verse, the last words 
he had said:
"Say: Had you remained in your houses, those for whom slaughter was ordained 
would have gone forth to the places where they would be slain."
That was on the last day of the month of Safar 203 A.H., in the city of Toos; 
its modern-day name is Mashhad.
