Jabir bin Abdullah reported,

Talq said, "The Prophet of Allah ﷺ sent me to the Banu al-Mustaliq. When I came back to him, he was praying on his camel. I spoke to him, but he gestured to me with his hand like this. I spoke again, and he gestured to me with his hand like this. I could hear him reciting and nodding his head."When he finished, he said, "What did you do regarding the matter I sent you for? Nothing prevented me from speaking to you except that I was praying."

Abu Dawud 926

حدثنا عبد الله بن محمد النفيلي حدثنا زهير حدثنا أبو الزبير

عن جابر قال

أرسلني نبي الله ﷺ إلى بنى المصطلق فأتيته وهو يصلي على بعيره فكلمته فقال لي بيده هكذا ثم كلمته فقال لي بيده هكذا وأنا أسمعه يقرأ ويومئ برأسه فلما فرغ قال ما فعلت في الذي أرسلتك فإنه لم يمنعني أن أكلمك إلا أني كنت أصلي
