The reciter: Isma'il narrated to us, Malik narrated to me, from 'Abd al-Rahman ibn al-Qasim, from his father, from 'A'ishah, who said:
Abu Bakr came to me while Allah's Messenger (ﷺ) was sleeping with his head on my thigh. Abu Bakr said (to me), "You have detained Allah's Messenger (ﷺ) and the people, and there is no water in this place." So he admonished me and struck my flanks with his hand, and nothing could stop me from moving except the reclining of Allah's Messenger (ﷺ) (on my thigh), and then Allah revealed the Divine Verse of Tayammum.
جاء أبو بكر رضي الله عنه، ورسول الله صلى الله عليه وسلم واضع رأسه على فخذي فقال: حبست رسول الله صلى الله عليه وسلم والناس، وليسوا على ماء، فعاتبني وجعل يطعن بيده في خاصرتي ، ولا يمنعني من التحرك إلا مكان رسول الله صلى الله عليه وسلم، فأنزل الله آية التيمم Sahih al-Bukhari 6844
