We set out with the Messenger of Allah ﷺ on one of his journeys until we reached Bayda, or Dhat al-Jaysh, where a necklace of mine broke and fell. The Messenger of Allah ﷺ stopped to search for it, and the people stopped with him. They were not near any water, nor did they have any with them.The people came to Abu Bakr and said, "Do you not see what Ayesha has done? She has kept the Messenger of Allah ﷺ and the people waiting in a place where there is no water and they have none with them."Abu Bakr
came in while the Messenger of Allah ﷺ was resting his head on my thigh, having fallen asleep. He said, "You have detained the Messenger of Allah ﷺ and the people in a place where there is no water and they have none with them."Ayesha said, Abu Bakr scolded me and said whatever Allah willed him to say, and he began poking me in my side with his hand. Nothing kept me from moving except the position of the Messenger of Allah ﷺ resting on my thigh.The Messenger of Allah ﷺ slept until morning without any water available, so Allah
revealed the verse of tayammum.Usayd bin Hudayr said, "This is not the first blessing you have brought, family of Abu Bakr."She said, We then made the camel I had been riding get up, and we found the necklace beneath it.
أخبرنا قتيبة عن مالك عن عبد الرحمن بن القاسم عن أبيه
خرجنا مع رسول الله ﷺ في بعض أسفاره حتى إذا كنا بالبيداء أو ذات الجيش انقطع عقد لي فأقام رسول الله ﷺ على التماسه وأقام الناس معه وليسوا على ماء وليس معهم ماء فأتى الناس أبا بكر رضي الله عنه فقالوا ألا ترى ما صنعت عائشة أقامت برسول الله ﷺ وبالناس وليسوا على ماء وليس معهم ماء فجاء أبو بكر رضي الله عنه ورسول الله ﷺ واضع رأسه على فخذي قد نام فقال حبست رسول الله ﷺ والناس وليسوا على ماء وليس معهم ماء قالت عائشة فعاتبني أبو بكر وقال ما شاء الله أن يقول وجعل يطعن بيده في خاصرتي فما منعني من التحرك إلا مكان رسول الله ﷺ على فخذي فنام رسول الله ﷺ حتى أصبح على غير ماء فأنزل الله عز وجل آية التيمم فقال أسيد بن حضير ما هي بأول بركتكم يا آل أبي بكر قالت فبعثنا البعير الذي كنت عليه فوجدنا العقد تحته
