Ahmed bin Hafs bin 'Abdullah أحمد بن حفص بن عبد الله · General Behavior (Kitab Al-Adab)

A Muslim is a Muslim’s brother: he does not wrong him or abandon him. If anyone cares for his brother’s need, Allah will care for his need ; if anyone removes a Muslim’s anxiety, Allah will remove from him, on account of it, one of the anxieties of the Day of resurrection ; and if anyone conceals a Muslim’s fault, Allah will conceal his fault on the Day of resurrection.
