Abu Hurairah reported,

The Messenger of Allah ﷺ said, "Do not envy one another, do not inflate prices against one another, do not hate one another, do not turn your backs on one another, and do not undercut one another in trade. Be servants of Allah, brothers to each other. A Muslim is the brother of another Muslim. He does not wrong him, abandon him, or look down on him. Piety is here," and he pointed to his chest three times. "It is enough evil for a man to despise his Muslim brother. Every Muslim is sacred to another Muslim, his blood, his property, and his honor."

حدثنا عبد الله بن مسلمة بن قعنب حدثنا داود يعني ابن قيس عن أبي سعيد مولى عامر بن كريز

عن أبي هريرة قال

قال رسول الله ﷺ لا تحاسدوا ولا تناجشوا ولا تباغضوا ولا تدابروا ولا يبع بعضكم على بيع بعض وكونوا عباد الله إخوانا المسلم أخو المسلم لا يظلمه ولا يخذله ولا يحقره التقوى هاهنا ويشير إلى صدره ثلاث مرات بحسب امرئ من الشر أن يحقر أخاه المسلم كل المسلم على المسلم حرام دمه وماله وعرضه
