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

I, too, performed a similar ablution, then I went and stood on his left. He drew me to his right and prayed as much as Allah wished, and again lay and slept till his breath sounds were heard. Later on the Mu'adh-dhin (call maker for the prayer) came to him and informed him that it was time for Prayer. The Prophet went with him for the prayer without performing a new ablution." (Sufyan said to `Amr that some people said, "The eyes of Allah's Apostle sleep but his heart does not sleep." `Amr replied, "I heard `Ubaid bin `Umar saying that the dreams of Prophets were Divine Inspiration, and then he recited the verse: 'I (Abraham) see in a dream, (O my son) that I offer you in sacrifice (to Allah)." (37.102) (See Hadith No. 183)

He rode till when he reached Al-Muzdalifa, he dismounted and performed ablution and a perfect one, The (call for) Iqama was pronounced and he led the Maghrib prayer. Then everybody made his camel kneel down at its place.
