حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا حَمَّادٌ، قَالَ سَمِعْتُ أَيُّوبَ، يَقُولُ كَذَبَ عَلَى الْحَسَنِ ضَرْبَانِ مِنَ النَّاسِ قَوْمٌ الْقَدَرُ رَأْيُهُمْ وَهُمْ يُرِيدُونَ أَنْ يُنَفِّقُوا بِذَلِكَ رَأْيَهُمْ وَقَوْمٌ لَهُ فِي قُلُوبِهِمْ شَنَآنٌ وَبُغْضٌ يَقُولُونَ أَلَيْسَ مِنْ قَوْلِهِ كَذَا أَلَيْسَ مِنْ قَوْلِهِ كَذَا

Hammad said: I heard Ayyub say: Two kinds of people have lied to al-Hasan: people who believed in free will and they intended that they publicise their belief by it; and people who had enmity with and hostility (for al-Hasan), saying: Did he not say so and so? Did he not say so and so? Translation Not Available
