Allahs Statement: ...And you find no water, then perform Tayammum with clean earth... (V.5:6)

The wife of the Prophet (ﷺ) : We set out with Allah's Messenger (ﷺ) on one of his journeys, and when we were at Baida' or at Dhat-al-Jaish, a necklace of mine was broken (and lost). Allah's Messenger (ﷺ) stayed there to look for it, and so did the people along with him. Neither were they at a place of water, nor did they have any water with them. So the people went to Abu Bakr As-Siddiq and said, "Don't you see what `Aisha has done? She has made Allah's Messenger (ﷺ) and the people, stay where there is no water and they have no water with them." Abu Bakr came while Allah's Messenger (ﷺ) was sleeping with his head on my thigh. He said (to me), "You have detained Allah's Messenger (ﷺ) and the people where there is no water, and they have no water with them." So he admonished me and said what Allah wished him to say, and he hit me on my flanks with his hand. Nothing prevented me from moving (because of pain! but the position of Allah's Messenger (ﷺ) on my thigh. So Allah's Messenger (ﷺ) got up when dawn broke and there was no water, so Allah revealed the Verse of Tayammum. Usaid bin Hudair said, "It is not the first blessing of yours, O the family of Abu Bakr." Then we made the camel on which I was riding, got up, and found the necklace under it.

A necklace of mine was lost at Al-Baida' and we were on our way to Medina. The Prophet (ﷺ) made his camel kneel down and dismounted and laid his head on my lap and slept. Abu Bakr came to me and hit me violently on the chest and said, "You have detained the people because of a necklace." I kept as motionless as a dead person because of the position of Allah's Messenger (ﷺ) ; (on my lap) although Abu Bakr had hurt me (with the slap). Then the Prophet (ﷺ) woke up and it was the time for the morning (prayer). Water was sought, but in vain; so the following Verse was revealed:-- "O you who believe! When you intend to offer prayer.." (5.6) Usaid bin Hudair said, "Allah has blessed the people for your sake, O the family of Abu Bakr. You are but a blessing for them."
