It was narrated from Abu Matar that He saw `Ali (رضي الله عنه) go to a young boy and buy a chemise from him for three dirhams. He put it on, and when it reached his wrists and ankles he said: Praise be to Allah Who has provided me with a garment with which to beautify myself before the people and cover my `awrah. It was said: Is this something you say yourself or are you narrating it from the Prophet (ﷺ) of Allah (ﷺ)? He said: This is something that I heard the Messenger of Allah (ﷺ) say when putting on a garment: “Praise be to Allah Who has provided me with a garment with which to beautify myself before the people and cover my `awrah.”
