وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، – وَاللَّفْظُ لَهُ – أَخْبَرَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ أَدْرَكَ عُمَرَ بْنَ الْخَطَّابِ فِي رَكْبٍ وَعُمَرُ يَحْلِفُ بِأَبِيهِ فَنَادَاهُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ “‏ أَلاَ إِنَّ اللَّهَ عَزَّ وَجَلَّ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ فَمَنْ كَانَ حَالِفًا فَلْيَحْلِفْ بِاللَّهِ أَوْ لِيَصْمُتْ ‏”‏. ‘Abdullah (b.
