سنن أبي داود

Narrated Abu Hurairah:

We went out with the Messenger of Allah (ﷺ) to Najd. When we reached Dhat ar-Riqa at Nakhl (or in a valley with palm trees) he met a group of the tribe of Ghatafan. The narrator then reported the tradition to the same effect, but his version is other than that of Haywah. He added to the words "when he bowed along with those who were with him and prostrated" the words "when they stood up, they retraced their footsteps to the rows of their companions". He did not mention the words "their back was towards the qiblah".
