Yahya b. Kathir al-‘Anbari said:

Qurrah b. Khalid used to tell us: O young people! Do not think that al-Hasan denied predestination, for his opinion (i.e., belief) was sunnah and sight.

حَدَّثَنَا ابْنُ الْمُثَنَّى، أَنَّ يَحْيَى بْنَ كَثِيرٍ الْعَنْبَرِيَّ، حَدَّثَهُمْ قَالَ كَانَ قُرَّةُ بْنُ خَالِدٍ يَقُولُ لَنَا يَا فِتْيَانُ لاَ تُغْلَبُوا عَلَى الْحَسَنِ فَإِنَّهُ كَانَ رَأْيُهُ السُّنَّةَ وَالصَّوَابَ ‏.‏
