This hadith has been reported on the authority of Husain With the same chain of transmitters but no mention is made of these words:" (I have been sent as a distributor), so I distribute amongst you."
حَدَّثَنَا رِفَاعَةُ بْنُ الْهَيْثَمِ الْوَاسِطِيُّ، حَدَّثَنَا خَالِدٌ، - يَعْنِي الطَّحَّانَ - عَنْ حُصَيْنٍ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ " فَإِنَّمَا بُعِثْتُ قَاسِمًا أَقْسِمُ بَيْنَكُمْ " .
