الطبراني:٩٢٩٥ – حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ عَنْ عَبْدِ الرَّزَّاقِ عَنِ الثَّوْرِيِّ وَابْنِ عُيَيْنَةَ عَنْ أَبِي إِسْحَاقَ عَنْ مَعْدِي كَرِبَ الْهَمْدَانِيِّ قَالَ

سَمِعْتُ ابْنَ مَسْعُودٍ يَقُولُ «لَا تَصْطَفُّوا بَيْنَ الْأَسَاطِينِ وَلَا تُصَلِّ وَبَيْنَ يَدَيْكَ قَوْمٌ يَمُرُّونَ»
