Chapter 269
Prohibition of Nursing Rancor and Enmity

Allah, the Exalted, says:

The believers are nothing else than brothers (in Islamic religion).” (49:10)

… humble towards the believers, stern towards the disbelievers ...” (5:54)

Muhammad (sallallaahu ’alayhi wa sallam) is the Messenger of Allah, and those who are with him are severe against disbelievers, and merciful among themselves.” (48:29)

1567. Anas bin Malik (May Allah be pleased with him) said: The Prophet (sallallaahu ’alayhi wa sallam) said, “Do not harbour grudge against one another, nor jealousy, nor enmity; and do not show your backs to one another; and become as fellow brothers and slaves of Allah. It is not lawful for a Muslim to avoid speaking with his brother beyond three days.”
[Al-Bukhari and Muslim].

1568. Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “The gates of Jannah are opened on Mondays and Thursdays, and then every slave (of Allah) is granted forgiveness if he does not associate anything with Allah in worship. But the person in whose heart there is rancour against his (Muslim) brother, they will not be pardoned and with regard to them it will be said twice: `Hold both of them until they are reconciled with each other.”’
