Hadith 1567
Anas bin Malik (May Allah be pleased with him) said:
وعن أنس رضي الله عنه أن النبي صلى الله عليه وسلم قال: "لا تباغضوا، ولا تحاسدوا ولا تدابروا، ولا تقاطعوا، وكونوا عباد الله إخوانًا، ولا يحل لمسلم أن يهجر أخاه فوق ثلاث" ((متفق عليه)).
The Prophet (ﷺ) 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].
In plain words
Do not let hatred, jealousy, or grudges settle between you; live instead as brothers. The hadith warns against staying silent toward a fellow Muslim out of resentment for more than three days.
