What did the angels ask Allah's forgiveness for when someone is at the Musalla (praying place) and he does not pass wind (Hadath) (saw)?
 Narrated Abu Huraira:                     Allah's Apostle said, "The angels keep on asking Allah's forgiveness for anyone of you, as long as he is at his Musalla (praying place) and he does not pass wind (Hadath). They say, 'O Allah! Forgive him, O Allah! be Merciful to him."
