Riyad as-Salihin, Book 18, Hadith 1567 (In-Book) ⓘ

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