Musalman ki Parda Poshi
Narrated by 'Abdullah bin Umar (رضی اللہ عنہ): Allah's Apostle (صلى الله عليه وسلم) 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."
Sahih Bukhari, Hadith no. 2443
