It was narrated from 'Aishah that:
She borrowed a necklace from Asma', and she lost it. The Prophet sent some people to look for it, and the time for prayer came so they prayed without ablution. When they came to the Prophet they complained to him about that, then the Verse of dry ablution was revealed. Usaid bin Hudair said: "May Allah reward you with good, for by Allah, nothing ever happens to you but Allah grants you a way out and blesses the Muslims thereby."
