The Messenger of Allah (pbuh) said : A muslim is a brother to a Muslim: Neither he wrongs him, nor hands him over (to another). And whoso comes in need of his brother , Allah comes in his need ;and whoso removes a calamity of a Muslim, Allah will remove a calamity from the calamities of the Resurrection Day, and whoso conceals the faults of a Muslim, Allah will conceal his sins on the Resurrection Day’ (Bukhari and Muslim)
