sahih

The hadith is narrated through Abu Mushir from Sa'id bin 'Abdil'Aziz except that the previous hadith through Marwan was the more complete of the two.

حَدَّثَنِيهِ أَبُو بَكْرِ بْنُ إِسْحَاقَ، حَدَّثَنَا أَبُو مُسْهِرٍ، حَدَّثَنَا سَعِيدُ بْنُ عَبْدِ الْعَزِيزِ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّ مَرْوَانَ أَتَمُّهُمَا حَدِيثًا ‏.‏
