Sunan Abi Dawud 25129
In-book no 4625حَدَّثَنَا 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 .
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.
