Bukhari :: Book 1 :: Volume 8 :: Hadith 369
the Prophet prayed in a Khamisa (a square garment) having marks. During the prayer, he looked at its marks. So when he finished the prayer he said, "Take this Khamisa of mine to Abu Jahm and get me his Inbijaniya (a woolen garment without marks) as it (the Khamisa) has diverted my attention from the prayer."
