Sahih Muslim Introduction 70
Hajjāj narrated to me, Sulaymān bin Harb narrated to us, he said, I heard Sallām bin Abī Mutī’ saying, it reached Ayyūb that I would go to Amr so he turned to me and said:
‘Have you seen a man whose Dīn you do not trust- how do you trust him regarding Ḥadīth?’
وَحَدَّثَنِي حَجَّاجٌ، حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ سَمِعْتُ سَلاَّمَ بْنَ أَبِي مُطِيعٍ، يَقُولُ بَلَغَ أَيُّوبَ أَنِّي آتِي عَمْرًا فَأَقْبَلَ عَلَىَّ يَوْمًا فَقَالَ أَرَأَيْتَ رَجُلاً لاَ تَأْمَنُهُ عَلَى دِينِهِ كَيْفَ تَأْمَنُهُ عَلَى الْحَدِيثِ
