Hamam bin Munabbih همام بن منبه بن كامل · The Book on Salat (Prayer)

Allah's Messenger said: "One of you does not cease to be in Salat as long as he is waiting for it. And the angels do not cease praying for one of you as long as he remains in the Masjid (saying): 'Allah! Forgive him. O Allah! Have mercy upon him' - as long as he does not commit Hadath." A man from Hadramawt said: "And just what is Hadath Abu Hurairah?" He said: "Breaking wind, or passing gas."
