ইংরেজিঃ হাদিস- ১৩৯

One should not repeat ablution if in doubt unless and until he is convinced (that he has lost his ablution by having Hadath)


Narrated `Abbas bin Tamim: My uncle asked Allah’s Messenger (sallallahu ‘alaihi wa sallam) 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.”
