Doubting that he has undergone ritual impurity

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. If a person performs Wudu’ and then doubts whether or not he had invalidated Wudu’, his doubts count for nothing and his Wudu’ is still valid. If a person is ritually impure and then doubts whether or not he performed Wudu’, he is still impure and the doubt is of no effect, because certainty cannot be removed by doubt and the ruling principle is that the original state remains in effect until the occurrence of that which overrules it is established. It is reported that a man complained to the Messenger of Allah (peace be upon him) that he imagined that he felt something during Salah (prayer), so the Prophet (peace be upon him) said: “He should not leave (prayer) unless he hears a sound or smells an odor.” (Related by the compilers of Sunan except Al-Tirmidhy). It is also reported that the Prophet (peace be upon him) said: “If any one of you feels something in his stomach, and is not sure whether something came out of him or not, he should not leave the Masjid (to renew his ablution) unless he hears a sound or smells an odor.” (Related by Muslim and Al-Tirmidhy) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
