Prohibition of the Treachery and Breaking one’s Covenant

Allah, the Exalted, says:

O you who believe! Fulfill (your) obligations.” (5:1)

And fulfill (every) covenant. Verily! The covenant will be questioned about.” (17:34)

1584. `Abdullah bin `Amr bin Al-`As (May Allah be pleased with them) said: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “Whosoever possesses these four characteristics is a sheer hypocrite; and anyone who possesses one of them possesses a characteristic of hypocrisy till he gives it up. These are: when he is entrusted with something, he proves dishonest; when he speaks, he tells a lie; when he makes a covenant, he proves treacherous; and when he quarrels, he behaves in very imprudent, evil, insulting manner.”
[Al-Bukhari and Muslim].

1585. Ibn Mas`ud, Ibn `Umar and Anas (May Allah be pleased with them) said: The Prophet (sallallaahu ’alayhi wa sallam) said, “For every one who breaks his covenant, there will be a (huge) flag on the Day of Resurrection and it will be said: `This flag proclaims a breach of covenant by so-and-so.”’
[Al-Bukhari and Muslim].

1586. Abu Sa`id Al-Khudri (May Allah be pleased with him) said: The Prophet (sallallaahu ’alayhi wa sallam) said, “Every one who breaks a covenant will have a flag by his buttocks on the Day of Resurrection. It will be raised higher according to the nature of his breach. Behold, there will be no greater a sin with respect to breaking the covenant than that of a ruler who breaks his covenant with the Muslim masses.”
[Muslim].

1587. Abu Hurairah (May Allah be pleased with him) reported: The Prophet (sallallaahu ’alayhi wa sallam) said, “Allah, the Exalted, says: `I will contend on the Day of Resurrection against three (types of) people: One who makes a covenant in My Name and then breaks it; one who sells a free man as a slave and devours his price; and one who hires a workman and having taken full work from him, does not pay him his wages.”’
[Al-Bukhari].
