حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا صَدَقَةُ بْنُ خَالِدٍ، حَدَّثَنَا عُثْمَانُ بْنُ أَبِي عَاتِكَةَ، عَنْ عَلِيِّ بْنِ يَزِيدَ، عَنِ الْقَاسِمِ، عَنْ أَبِي أُمَامَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏
"‏ عَلَيْكُمْ بِهَذَا الْعِلْمِ قَبْلَ أَنْ يُقْبَضَ وَقَبْضُهُ أَنْ يُرْفَعَ ‏"‏ ‏.‏ وَجَمَعَ بَيْنَ إِصْبَعَيْهِ الْوُسْطَى وَالَّتِي تَلِي الإِبْهَامَ هَكَذَا ثُمَّ قَالَ ‏"‏ الْعَالِمُ وَالْمُتَعَلِّمُ شَرِيكَانِ فِي الأَجْرِ وَلاَ خَيْرَ فِي سَائِرِ النَّاسِ ‏"‏ ‏.‏
