Oppression – 15th Dhul Qa'dah 1433 (1st October 2012)

Narrated 'Abdullah bin Umar (Radi-Allahu 'anhu):

Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) said, "A Muslim is a brother
of another Muslim, so he should not oppress him, nor should he hand him
over to an oppressor. Whoever fulfilled the needs of his brother, Allah
will fulfill his needs; whoever brought his (Muslim) brother out of a
discomfort, Allah will bring him out of the discomforts of the Day of
Resurrection, and whoever screened a Muslim, Allah will screen him on the
Day of Resurrection."
