Ibn ‘Awn said:I was a prisoner in Syria. A man called me from behind. I turned towards him and suddenly found that it was Raja b. Haiwah. He said: Abu ‘Awn, what is this that the people are telling about al-Hasan? I said: They are much lying to al-Hasan.
حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ، حَدَّثَنَا سُلَيْمٌ، عَنِ ابْنِ عَوْنٍ، قَالَ كُنْتُ أَسِيرُ بِالشَّامِ فَنَادَانِي رَجُلٌ مِنْ خَلْفِي فَالْتَفَتُّ فَإِذَا رَجَاءُ بْنُ حَيْوَةَ فَقَالَ يَا أَبَا عَوْنٍ مَا هَذَا الَّذِي يَذْكُرُونَ عَنِ الْحَسَنِ قَالَ قُلْتُ إِنَّهُمْ يَكْذِبُونَ عَلَى الْحَسَنِ كَثِيرًا .
