The Prophet SAWS said:
“The gates of Paradise are opened on Mondays and Thursdays, and every slave who does not associate anything with Allah SWT is forgiven, except for the man who has a grudge against his brother.
It is said: wait for these two until they reconcile, wait for these two until they reconcile, wait for these two until they reconcile.”
[Muslim & Abu Dawood]
Anas bin Malik (May Allah be pleased with him) said: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “Do not desert (stop talking to) one another, do not nurse hatred towards one another, do not be jealous of one another, and become as fellow brothers and slaves of Allah. It is not lawful for a Muslim to stop talking to his brother (Muslim) for more than three days.”
[Al-Bukhari and Muslim]
May we never have that sort of pride or anger towards another that we forsake them.
