Narrated `Urwa's father:: Aisha said, "I borrowed a necklace from Asma' and it was lost. So Allah's Messenger (sallallahu ‘alaihi wa sallam) sent a man to search for it and he found it. Then the time of the prayer became due and there was no water. They prayed (without ablution) and informed Allah's Messenger (sallallahu ‘alaihi wa sallam) about it, so the verse of Tayammum was revealed." Usaid bin Hudair said to `Aisha, "May Allah reward you. By Allah, whenever anything happened which you did not like, Allah brought good for you and for the Muslims in that." Al-Jurf and the time for the `Asr prayer became due while he was at Marbad-An-Na`am (sheepfold), so he (performed Tayammum) and prayed there and then entered Medina when the sun was still high but he did not repeat that prayer.
