269. Chapter: On forbidding mutual rancour, cutting one other off and mutual hostility

Allah says, "The believers are brothers" (49:10)

and the Almighty says, "Humble to the believers, fierce to the unbelievers." (5:54)

The Almighty says, "Muhammad is the Messenger of Allah; and those who are with him are fierce to the unbelievers, merciful to one another." (48:29)

1567. Anas reported that the Prophet, may Allah bless him and grant him peace, said, "Do not hate one another nor envy one another nor act in a hostile way towards one another nor cut one another off. Be slaves of Allah, brothers. It is not lawful for a Muslim to cut himself off from his brother for more than three days." [Agreed upon]

1568. Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "The gates of the Garden are opened on Mondays and Thursdays and every slave who does not associate anything with Allah is forgiven except the man between whom and his brother there is rancour. It is said, 'Wait until these two make it up! Wait until these two make it up!'" [Muslim]

One variant has, "Actions are presented every Thursday and Monday."
