Sincerity in Work
If we want to define sincerity we can define it by: it is to become sincere in your intention or to defend toward work from any thing except from God Almighty. The sanctity of the work and the loftiness of its value are subjected to the existence of sincerity through it. This is reverted to our works, in which they might be close to God, but invaluable if they weren't done sincerely.
It was mentioned about the Messenger of Allah (peace be upon him and his household) the following: "If you did a work, do it sincerely, because it won't be accepted by God if it wasn't done sincerely".
Prophet Mohammad (peace be upon him and his household) said: "Works are related to intentions, and every person is accounted according to his intention; hence the person who works for the sake of Allah and his prophet will be rewarded for that, while the one who is working for the world and what it contains, then he will be accounted according to this."
The believer person, who works for the sake of Allah, shouldn't be hypocrite, for it is a frustrated plague for every work he vitiates.
Imam Jaafar Al-Sadiq (A.S.) told Abbad Al-Bacary: "O man, don't ever be hypocrite, for the person who works for sake other than God's one, God will entrusted him to the one who is working for his sake".
He (A.S.) adds to say: "Let all your works be for the sake of Allah and not for the people, since what is done for the sake of Allah, will be for God, but what is done for the sake of people, won't be raised to God, and will not give you rewards for it".
Imam (A.S.) adds to say: "Every act of hypocrite is polytheism; he who works for people, people will reward him, while the one who works for the sake of Allah, will be reward by Him".
The Commander of the Faithful (A.S.) hinted to the signs of the hypocrite by saying: "He becomes active when he sees the people, becomes sluggish while being alone, and likes to be praised for all what he does".
Prophet Mohammad (peace be upon him and his household) said: "Each right has its reality, and not any person reaches the reality of sincerity so that not to love to be praised for a thing that is made by God".
Besides, it was narrated about some of the sincere people that they might be at risk because he keeps afraid to loose his sincerity at the last moment of his life.
All the scholars are perishable, except those who work for the sake of Allah, and the workers are the ones who are sincere, and those ones are at risk, since at the last moment of there life they might fall back from being like this.
Imam Ali (A.S.) talked about the difficulty of sincerity in working by saying: "clarifying the work is harder than the work by itself, and letting the intention to be sincere from corruption is harder for the workers from struggling all the life".
Eventually, all praise is due to Allah, the Lord of the worlds.
