حَدَّثَنَا حَسَنُ بْنُ الرَّبِيعِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، وَهِشَامٍ، عَنْ مُحَمَّدٍ، وَحَدَّثَنَا فُضَيْلٌ، عَنْ هِشَامٍ، قَالَ وَحَدَّثَنَا مَخْلَدُ بْنُ حُسَيْنٍ، عَنْ هِشَامٍ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، قَالَ إِنَّ هَذَا الْعِلْمَ دِينٌ فَانْظُرُوا عَمَّنْ تَأْخُذُونَ دِينَكُمْ ‏.‏
