Narrated Abu Huraira (Radi-Allahu 'anhu):

Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) said, "The prayer of a
person who does Hadath (passes urine, stool or wind) is not accepted till
he performs (repeats) the ablution." A person from Hadaramout asked Abu
Huraira, "What is Hadath?" Abu Huraira replied, "Hadath means the passing
of wind from the anus."
