أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا النَّضْرُ، قَالَ أَنْبَأَنَا شُعْبَةُ، عَنْ سُلَيْمَانَ، قَالَ سَمِعْتُ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، وَالأَسْوَدِ، عَنْ عَبْدِ اللَّهِ، فَذَكَرَ نَحْوَهُ .
It was narrated that Sulaiman said: "I heard Ibrahim (narrate) from 'Alqamah and Al-Aswad from 'Abdullah," and he narrated something similar.
