Sahih al-Bukhari
Ablutions (Wudu')
Chapter: One should not repeat ablution if in doubt unless and until he is convinced (that he has lost his ablution by having Hadath)
Narrated `Abbad bin Tamim:
My uncle asked Allah's Messenger (ﷺ) about a person who imagined to have passed wind during the prayer. Allah' Apostle replied: "He should not leave his prayers unless he hears sound or smells something."
