✦ Narrated Abu Hurairah Radi Allahu anhu : The Prophet peace be upon him said: It is not allowable for a believer to keep away ( or be annoyed ) from a believer for more than three days. If three days pass, he should meet him and give him a salutation, and if he replies to it they will both have shared in the reward; but if he does not reply he will bear his sin 

Sunan Abu Dawud, Book 41, 4894-Sahih

✦ Narrated AbuHurairah Radi Allahu anhu : The Prophet peace be upon him said: It is not allowable for a Muslim to keep apart from his brother for more than three days, for one who does so and dies will enter Hell. 

Sunan Abu Dawud, Book 41, 4896 -Sahih

✦ Abu Huraira Radi allahu anhu reported The Prophet peace be upon him said The gates of Paradise are opened 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.
