Sahih Muslim Introduction 24
Hasan bin Alī al-Hulwānī narrated to us, Yahyā bin Ādam narrated to us, Ibn Idrīs narrated to us, on authority of al-A’mash, on authority of Abī Ishāq who said:
‘When they narrated these things after Alī, may Allah be pleased with him, a man from the companions of Alī said: ‘May Allah curse them. Did they corrupt every [type of] knowledge!?’
حَدَّثَنَا حَسَنُ بْنُ عَلِيٍّ الْحُلْوَانِيُّ، حَدَّثَنَا يَحْيَى بْنُ آدَمَ، حَدَّثَنَا ابْنُ إِدْرِيسَ، عَنِ الأَعْمَشِ، عَنْ أَبِي إِسْحَاقَ، قَالَ لَمَّا أَحْدَثُوا تِلْكَ الأَشْيَاءَ بَعْدَ عَلِيٍّ - رضى الله عنه - قَالَ رَجُلٌ مِنْ أَصْحَابِ عَلِيٍّ قَاتَلَهُمُ اللَّهُ أَىَّ عِلْمٍ أَفْسَدُوا ‏.‏
