Sahih Muslim Book 4, Hadith Number 1162.

Chapter : It is forbidden to cry out for finding out the lost thing in the mosque.

Abu Huraira reported: The Messenger of Allah (may peace be upon him) said: The devil takes to his heels breaking wind when the prayer begins. and the rest is the same but with this addition: “He (the devil) makes him think of pleasant things (or things productive of enjoyment) and of the things wished for, and reminds him of such needs which he had forgotten.”
