حَدَّثَنَا مُسَدَّدٌ، قَالَ: حَدَّثَنَا بِشْرُ بْنُ الْفَضْلِ، قَالَ: حَدَّثَنَا أَبُو مَسْلَمَةَ، عَنْ أَبِي نَضْرَةَ، عَنْ مُطَرِّفٍ قَالَ: قَالَ أَبِي: انْطَلَقْتُ فِي وَفْدِ بَنِي عَامِرٍ إِلَى النَّبِيِّ صلى الله عليه وسلم، فَقَالُوا: أَنْتَ سَيِّدُنَا، قَالَ: السَّيِّدُ اللَّهُ، قَالُوا: وَأَفْضَلُنَا فَضْلاً، وَأَعْظَمُنَا طَوْلاً، قَالَ: فَقَالَ: قُولُوا بِقَوْلِكُمْ، وَلاَ يَسْتَجْرِيَنَّكُمُ الشَّيْطَانُ.
Mutarrif reported that his father said, "I went in the delegation of the Banu 'Amir to the Prophet, may Allah bless him and grant him peace. They said, 'You are our master.' He said, 'The Master is Allah.' They said, 'The best of us in excellence and the greatest of us in generosity.' He said, 'Say what you like, but do not let Shaytan provoke you.'"
