Actions while Praying
Bukhari :: Book 2 :: Volume 22 :: Hadith 301
Narrated Abu Huraira:
The Prophet once offered the prayer and said, "Satan came in front of me and tried to interrupt my prayer, but Allah gave me an upper hand on him and I choked him. No doubt, I thought of tying him to one of the pillars of the mosque till you get up in the morning and see him. Then I remembered the statement of Prophet Solomon, 'My Lord ! Bestow on me a kingdom such as shall not belong to any other after me.' Then Allah made him (Satan) return with his head down (humiliated)."
