It is narrated from Sayyiduna Wathilah that I heard the Prophet (peace be upon him) say: The life, honor, and wealth of a Muslim are sacred to another Muslim. Every Muslim is a brother to another Muslim; he does not oppress him nor does he abandon him. Taqwa is here—saying this, the Prophet (peace be upon him) pointed towards his heart. And then he said: It is enough evil for a person to consider his Muslim brother insignificant.
