أَخْبَرَنَا سَعِيدُ بْنُ عَامِرٍ ، قَالَ : كَانَ سَلَّامٌ يَذْكُرُ، عَنْ أَيُّوبَ ، قَالَ :" إِذَا أَرَدْتَ أَنْ تَعْرِفَ خَطَأَ مُعَلِّمِكَ، فَجَالِسْ غَيْرَهُ "

Saeed bin Amir told us, he said: Salam was mentioning, on the authority of Ayoub, he said: “If you want to know the mistake of your teacher, sit with someone else.”
