حَدَّثَنِي ابْنُ قُهْزَاذَ، قَالَ: سَمِعْتُ وَهْبًا يَقُولُ عَنْ سُفْيَانَ عَنِ ابْنِ الْمُبَارَكِ، قَالَ: بَقِيَّةُ صَدُوقُ اللِّسَانِ وَلَكِنَّهُ يَأْخُذُ عَمَّنْ أَقْبَلَ وَأَدْبَرَ.
Translation: Ibn Quhzādh narrated to me: “I heard Wahb relate, on the authority of Sufyān, from Ibn al-Mubārak, who said: ‘Baqiyyah is truthful of tongue, but he takes reports from whoever comes and goes.’”
Ṣadūq al-lisān describes his own truthfulness; “takes from whoever comes and goes” criticizes his source selection. A personally truthful carrier may still transmit unreliable material when his teachers or links have not been adequately assessed.
