أَخْبَرَنَا مُحَمَّدُ بْنُ يُوسُفَ ، عَنْ سُفْيَانَ ، عَنْ لَيْثٍ ، قَالَ : قَالَ لِي طَاوُسٌ :" مَا تَعَلَّمْتَ، فَتَعَلَّمْ لِنَفْسِكَ، فَإِنَّ النَّاسَ قَدْ ذَهَبَتْ مِنْهُمْ الْأَمَانَةُ "

Muhammad ibn Yusuf told us, on the authority of Sufyan, on the authority of Laith, he said: Tawus said to me: “Whatever you learn, learn for yourself, for the people have gone.” “Among them is trustworthiness.”
