It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When any one of you is performing prayer, Satan comes to him and pulls the hair at his back, causing the person to imagine that he has broken his ablution due to passing wind. In such a situation, no one should go for ablution unless he hears a sound or perceives a smell.
