The Believer's Sanctity
Islam granted for the humanitarian soul a very great honorable status, in which it praised the soul's animation and dispraised killing it in its Holy Quran, so it was mentioned: ﴾whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely.﴿ Besides, it was narrated that the cause of naming the believer as such is due to the reason that he is a source of safety for the people for them selves and for their money as well. Concerning this, it was mentioned about the Messenger of Allah (peace be upon him and his household) the following: "I want to tell you why the believer is named as such, because people are loyal with themselves and with their money"; Imam Ali added to say with this respect: "The believers' goods are hoped and their evils are safe".
Islam glorified the believer's sanctity, so it prohibited harming him, and granted for him self, his family, and his wealth the inaccessibility that forbids the aggression on him.
It was narrated that the Messenger of Allah (peace be upon him and his household) looked once to the Kaba and said: "Welcome with the house, o how much you are great and how much your sanctity is by God?! I swear by God Almighty that the believer's sanctity is greater than you".
From this point, Prophet Mohammad and his household (peace be upon them all) warned from inflicting damage on the believer. The Messenger of Allah said concerning this: "He who hurts a believer will be as if hurting me". Imam Al-Sadiq (A.S.) added saying: God Almighty said: "war will start between Me and the person who hurts a believer"; in another tradition for him, he said: "On the day of resurrection, a caller will call: where are the alienations for My guardians, then a group of people will come with no flesh on their faces. Then it will be said: those are the people who had hurt the believers, trapped for them, opposed and resisted them, and treated them hardly because of their religion. After that, it will be ordered to throw them in the hell".
Moreover, when we talk about hurt, we told just mean by it a direct hurt, but helping in hurting the others is not less than the hurt as it is; Abi Abdullah said: "He who helped a person in hurting a believer even in a single word, on the day of resurrection, will meet God with a writing between his eyes: he is despaired from My mercy".
On the other side, Imam Zein al-Abideen (A.S.) said: "He who refrain from hurting the others is considered to have a complete mind, and hence this will let him feel comfortable and has peace of mind". Hence, this is one of the believers' attributes, as Abi Abed Allah said: "It is obligatory for the believer person to have 8 attributes which are: A grave one during distress, patient during affliction, thankful during weal, satisfied with what God granted to him, don't oppress the enemies, don't prejudice against his friends, and even he was tired, he let the others feel relax and comfort by not hurting them".
Furthermore, many stories affirm that hurting the believer is prohibited even it was restricted to frightening and scaring him. Imam Ali (A.S.) said: "It is not lawful for a person to frighten a Muslim one".
The sanctity of frightening the others starts from a look, in which if you looked in a bad way toward a person, this will cause to great punishment as was mentioned in the hadith about the Messenger of Allah (peace be upon him and his household): "He who looks toward a Muslim in a strange way aiming from that to frighten him, then God Almighty will frighten him when there is no shadow other than His shadow".
The greatness of the sanctity will be more when it is translated from a look to become an act of frightening especially with the weapon as the Messenger of Allah (peace be upon him and his household) said concerning this: "The one who draw his weapon toward a Muslim person, angels will keep on cursing him until he put it aside him".
Eventually, all praise is due to Allah, the Lord of the worlds.
