“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.’”  

قَدِمْتُ الْمَدِينَةَ فَرَأَيْتُ النَّبِيَّ ﷺ قَائِمًا عَلَى الْمِنْبَرِ وَبِلاَلٌ قَائِمٌ بَيْنَ يَدَيْهِ مُتَقَلِّدٌ سَيْفًا وَإِذَا رَايَةٌ سَوْدَاءُ فَقُلْتُ مَنْ هَذَا قَالُوا هَذَا عَمْرُو بْنُ الْعَاصِ قَدِمَ مِنْ غَزَاةٍ  

It was narrated from Jabir bin ‘Abdullah that the Prophet ﷺ entered Makkah on the Day of the Conquest, and his standard was white.  

أَنَّ النَّبِيَّ ﷺ دَخَلَ مَكَّةَ يَوْمَ الْفَتْحِ وَلِوَاؤُهُ أَبْيَضُ  

It was narrated from Ibn ‘Abbas that the flag of the Messenger of Allah ﷺ was black, and his standard was white.  

أَنَّ رَايَةَ رَسُولِ اللَّهِ ﷺ كَانَتْ سَوْدَاءَ وَلِوَاؤُهُ أَبْيَضُ
