Sahih Muslim , Book 32, Hadith 6222 (USC-MSA) ⓘ
Abu Huraira reported Allah's Messenger as saying: The gates of Paradise are not opened but on two days, Monday and Thursday. and then every servant (of Allah) is granted pardon who does not associate anything with Allah except the person in whose (heart) there is rancour against his brother. And it would be said: Look towards both of them until there is reconciliation; look toward both of them until there is reconciliation; look towards both of them until there is reconciliation. This hadith has been narrated on the authority of Suhail who narrated it on the authority of his father with the chain of transmitters of MaIik, but with this variation of wording:, (Those would not be granted pardon) who bycott each other."
