Anas bin Malik (May Allah be pleased with him) said:
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].

وعن أنس رضي الله عنه أن النبي ﷺ قال: "لا تباغضوا، ولا تحاسدوا ولا تدابروا، ولا تقاطعوا، وكونوا عباد الله إخوانًا، ولا يحل لمسلم أن يهجر أخاه فوق ثلاث" ((متفق عليه)).
