حَدَّثَنَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا عُبَيْدُ بْنُ سَعِيدٍ الأُمَوِيُّ، حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، بِهَذَا الإِسْنَادِ وَقَالَ “ فَلْيَتَحَرَّ الصَّوَابَ ” .
This hadith has been narrated by Mansur with the same chain of transmitters with the words:
He should aim at what is correct and complete.”
