أَخْبَرَنَا مُحَمَّدُ بْنُ أَحْمَدَ ، قَالَ : سَمِعْتُ سُفْيَانَ ، يَقُولُ : قَالَ عُبَيْدُ اللَّهِ :" شِنْتُمْ الْعِلْمَ وَأَذْهَبْتُمْ نُورَهُ، وَلَوْ أَدْرَكَنِي وَإِيَّاكُمْ عُمَرُ رِضْوَانُ الله عَلَيْهِ لَأَوْجَعَنَا "

Muhammad ibn Ahmad informed us, saying: I heard Sufyan saying: Ubayd Allah said: “You distorted knowledge and took away its light, even if it reached me.” And beware of Omar, may God be pleased with him, for it pains us.”
