It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: A Muslim is the brother of a Muslim; he does not oppress him nor does he abandon him helpless. Whoever strives to fulfill the need of his brother, Allah Almighty remains engaged in fulfilling his need. Whoever removes a difficulty from a Muslim, Allah Almighty will remove one of his difficulties from the difficulties of the Day of Resurrection. And whoever conceals (the faults of) a Muslim, Allah Almighty will conceal him on the Day of Resurrection.
