The Book of Jihad and Expeditions
وَحَدَّثَنَاهُ عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَإِسْحَاقُ، جَمِيعًا عَنْ جَرِيرٍ، ح وَحَدَّثَنِي أَبُو سَعِيدٍ، الأَشَجُّ حَدَّثَنَا وَكِيعٌ، كِلاَهُمَا عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ . وَفِي حَدِيثِهِمَا إِلَى أَمْرٍ يُفْظِعُنَا.The same tradition has been narrated through a different chain of transmitters on the authority of A'mash. This version contains the words:Ila amrin yofzi'una instead of Ila amrin na'rifuhu
From Sahih Muslim, whose reports the scholars accept as authentic.
