What did the Prophet Muhammad (saw) say about the devil distracting a person while praying?
 Abu Huraira reported:                      The Messenger of Allah (may peace be upon him) said: When any one of you stands up to pray, the devil comes to him and confuses him to that he does not know how much he has prayed. If any one of you has such an experience he should perform two prostrations while sitting down (in qa'da).
