Sahih Muslim intro-24
حَدَّثَنَا عَلِيُّ بْنُ خَشْرَمٍ، أَخْبَرَنَا أَبُو بَكْرٍ، - يَعْنِي ابْنَ عَيَّاشٍ - قَالَ سَمِعْتُ الْمُغِيرَةَ، يَقُولُ لَمْ يَكُنْ يَصْدُقُ عَلَى عَلِيٍّ - رضى الله عنه - فِي الْحَدِيثِ عَنْهُ إِلاَّ مِنْ أَصْحَابِ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ .
Alī bin Khashram narrated to us, Abū Bakr, meaning Ibn Ayyāsh, informed us, he said ‘I heard al-Mughīrah saying:
‘There are no Ḥadīth on authority of Alī, may Allah be pleased with him, that are confirmed except from the companions of Abd Allah bin Mas’ūd.’
