"A Muslim is a brother of another Muslim, he should not oppress him, nor should he hand him over to an oppressor. Whoever fulfilled the needs of his brother, Allâh will fulfil his needs; whoever brought his (Muslim) brother out of a discomfort, Allâh will bring him out of the discomforts of the Day of Resurrection, and whoever screened a Muslim, Allâh will screen him on the Day of Resurrection."
