“I came to Al-Madinah and saw the Prophet ﷺ standing on the pulpit, and Bilal standing in front of him, with his sword by his side, and (I saw) a black flag. I said: ‘Who is this?’ He said: ‘This is ‘Amr bin ‘As, who has just come back from a campaign.’” (Using translation from Ibn Mājah 2816)
قَدِمْتُ الْمَدِينَةَ فَرَأَيْتُ النَّبِيَّ ﷺ قَائِمًا عَلَى الْمِنْبَرِ وَبِلَالٌ قَائِمٌ بَيْنَ يَدَيْهِ مَتَقَلِّدًا سَيْفًا وَإِذَا رَايَاتٌ سُودٌ فَقُلْتُ مَا هَذِهِ؟ قَالُوا عَمْرُو بْنُ الْعَاصِ قَدِمَ مِنْ غَزَاةٍ
