It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When any one of you is in prayer, Satan comes to him and entices him just as a person entices his animal. When he gains control over him, he releases wind between his buttocks so as to mislead him from the prayer. Therefore, if any one of you experiences such a condition, he should not leave the prayer unless he hears a sound or perceives a smell.
