Malik related to me from Hisham ibn Urwa from his father that the
Messenger of Allah, may Allah bless him and grant him peace, wore a
fine striped garment f rom Syria, and then gave it to Abu Jahm and
took a plain, rough, garment in return. Abu Jahm asked, "Messenger of
Allah! Why?" He said, "I looked at its stripes in the prayer."
