Sahih al-Bukhari 334

It is related that 'A'isha, the wife of the Prophet, said, "We went out with the Messenger of Allah, may Allah bless him and grant him peace, on one of his journeys until, when we had reached al-Bayda, or Dhat al-Jaysh, my necklace broke and the Messenger of Allah, may Allah bless him and grant him peace, stayed to look for it and everyone else stayed with him. There was no water there, so the people went to Abu Bakr as-Siddiq and said, 'Do you not see what 'A'isha has done? She has caused the Messenger of Allah, may Allah bless him and grant him peace, and everyone else to halt at a place where there is no water for them nor are they carrying any water with them?' Abu Bakr came and found that the Messenger of Allah, may Allah bless him and grant him peace, had gone to sleep with his head against my thigh. He said, 'You have held up the Messenger of Allah, may Allah bless him and grant him peace, and everyone else in a place where there is no water and they are not carrying any water with them!' Abu Bakr rebuked me saying what Allah wished him to say and started to poke me in the side with his hand and the only reason I did not move was that the Messenger of Allah, may Allah bless him and grant him peace, was against my thigh. At first light the Messenger of Allah, may Allah bless him and grant him peace, got up and found that there was no water. Then Allah sent down the verse of tayammum. So they did tayammum." Usayd ibn al-Hudayr said, 'Family of Abu Bakr, this is not the first blessing you have brought!'." 'A'isha continued, "We made the camel I was on get up and found the necklace underneath it."
