Jami` at-Tirmidhi, Volume 5, Book 44, Hadith 3274 (DarusSalam) ⓘ
Narrated Abu Wa'il: that Al-Harith bin Yazid Al-Bakri said: "I arrived in Al-Madinah and entered the Masjid and found it full with the people and I also noticed a black banner raised high, while Bilal was holding a sword before the Messenger of Allah. I said: 'What is the matter with the people?' They said: 'He intends to send 'Amr bin Al-'As somewhere.'" So he mentioned the Hadith in its entirety, similar in meaning to the narration of Sufyan bin 'Uyainah (#3273). He said: He is also called Al-Harith bin Hassan.
حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا زَيْدُ بْنُ حُبَابٍ، حَدَّثَنَا سَلاَّمُ بْنُ سُلَيْمَانَ النَّحْوِيُّ أَبُو الْمُنْذِرِ، حَدَّثَنَا عَاصِمُ بْنُ أَبِي النَّجُودِ، عَنْ أَبِي وَائِلٍ، عَنِ الْحَارِثِ بْنِ يَزِيدَ الْبَكْرِيِّ، قَالَ قَدِمْتُ الْمَدِينَةَ فَدَخَلْتُ الْمَسْجِدَ فَإِذَا هُوَ غَاصٌّ بِالنَّاسِ وَإِذَا رَايَاتٌ سُودٌ تَخْفُقُ وَإِذَا بِلاَلٌ مُتَقَلِّدٌ السَّيْفَ بَيْنَ يَدَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم قُلْتُ مَا شَأْنُ النَّاسِ قَالُوا يُرِيدُ أَنْ يَبْعَثَ عَمْرَو بْنَ الْعَاصِ وَجْهًا فَذَكَرَ الْحَدِيثَ بِطُولِهِ نَحْوًا مِنْ حَدِيثِ سُفْيَانَ بْنِ عُيَيْنَةَ بِمَعْنَاهُ . قَالَ وَيُقَالُ لَهُ الْحَارِثُ بْنُ حَسَّانَ أَيْضًا .
