وَحَدَّثَنِي ابْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ سِمَاكٍ، بِهَذَا الإِسْنَادِ مِثْلَهُ ‏.‏ قَالَ سِمَاكٌ وَسَمِعْتُ أَخِي، يَقُولُ قَالَ جَابِرٌ فَاحْذَرُوهُمْ ‏.‏

This hadith has been narrated on the authority of Simak with the same chain of transmitters. and Simak said: I heard my brother say that jabir had stated: Be on your guard against them.
