Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ النُّفَيْلِيُّ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا أَبُو الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ أَرْسَلَنِي نَبِيُّ اللَّهِ صلى الله عليه وسلم إِلَى بَنِي الْمُصْطَلِقِ فَأَتَيْتُهُ وَهُوَ يُصَلِّي عَلَى بَعِيرِهِ فَكَلَّمْتُهُ فَقَالَ لِي بِيَدِهِ هَكَذَا ثُمَّ كَلَّمْتُهُ فَقَالَ لِي بِيَدِهِ هَكَذَا وَأَنَا أَسْمَعُهُ يَقْرَأُ وَيُومِئُ بِرَأْسِهِ فَلَمَّا فَرَغَ قَالَ " مَا فَعَلْتَ فِي الَّذِي أَرْسَلْتُكَ فَإِنَّهُ لَمْ يَمْنَعْنِي أَنْ أُكَلِّمَكَ إِلاَّ أَنِّي كُنْتُ أُصَلِّي " .
The prophet of Allah(ﷺ) sent me to Banu al-Mustaliq. When I returned to him, he was praying on his camel. I talked to him; he made a sign to me with his hand like this. I again talked to him; he made a sign to me with his hand like this. I was hearing him reciting the Qur’an and he was making a sign with his head. When he finished his prayer, he said; what did you do about the mission for which I had sent you; nothing prevented me from talking to you except that I was praying.
