86. Chapter: On Fulfilling contracts and keeping promises

Allah says, "Fulfil your contracts. Contracts will be asked about," (17:34)

and the Almighty says, "Be true to Allah's contract when you have agreed to it." (16:91)

The Almighty says, "O you who believe! Fulfil your contracts," (5:1)

and the Almighty says, "O you who believe! Why do you say what you do not do? It is deeply abhorrent to Allah that you say what you do not do." (61:2-3)

689. Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "There are three signs of a hypocrite: whenever he speaks, he lies; whenever he makes a promise, he breaks it; and whenever he is trusted, he betrays his trust." [Agreed upon]

It is added in a variant of Muslim, "Even if he fasts and prays and claims that he is a Muslim."

690. 'Abdullah ibn 'Amr ibn al-'As reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "If anyone has four characteristics, he is a pure hypocrite, and if anyone has one of them, he has an aspect of hypocrisy until he gives it up: whenever he is trusted, he betrays his trust; whenever he speaks, he lies; whenever he makes an agreement, he breaks it; and whenever he quarrels, he deviates from the truth speaks falsely." [Agreed upon]

691. Jabir ibn 'Abdullah said, "The Prophet, may Allah bless him and grant him peace, said, 'If the money from Bahrayn comes, I will give you such-and-such.' The money from Bahrayn did not come until after the Prophet had died. When the money of Bahrayn arrived, Abu Bakr commanded that it be announced, 'Whoever has a promise from the Prophet, may Allah bless him and grant him peace, or a debt should come to us.' I came to him and said, 'The Prophet, may Allah bless him and grant him peace, told me such-and-such.' He gave me a double handful and I counted them and there were five hundred. He said, 'Take twice as much again.'" [Agreed upon]
