وعن أبي هريرة رضي الله عنه
قال: قال رسول الله صلى الله عليه وسلم: «المسلم أخو المسلم لا يخونه ولا يكذبه ولا يخذله، كل المسلم على المسلم حرام عرضه وماله ودمه، التقوى ههنا، بحسب امرئ من الشر أن يحقر أخاه المسلم»
Messenger of Allah (sallallahu alayhi wa sallam) said, “A Muslim is a brother to a Muslim. He should neither deceive him nor lie to him, nor leave him without assistance. Everything belonging to a Muslim is inviolable for a Muslim; his honour, his blood and property. Piety is here (and he pointed out to his chest thrice). It is enough for a Muslim to commit evil by despising his Muslim brother.”.
