The Prophet ﷺ entered Mecca in the year of the Conquest while he had a black turben over him.  

أَنَّ رَسُولَ اللَّهِ ﷺ دَخَلَ عَامَ الْفَتْحِ مَكَّةَ وَعَلَيْهِ عِمَامَةٌ سَوْدَاءُ  

I saw the Prophet ﷺ on the pulpit and he wore a black turban, and he let both the ends hang between his shoulders.  

رَأَيْتُ النَّبِيَّ ﷺ عَلَى الْمِنْبَرِ وَعَلَيْهِ عِمَامَةٌ سَوْدَاءُ قَدْ أَرْخَى طَرَفَيْهَا بَيْنَ كَتِفَيْهِ  

Ali quoting his father said: Rukanah wrestled with the Prophet ﷺ and the Prophet ﷺ threw him on the ground. Rukanah said: I heard the Prophet ﷺ say: The difference between us and the polytheists is that we wear turbans over caps.  

أَنَّ رُكَانَةَ صَارَعَ النَّبِيَّ ﷺ فَصَرَعَهُ النَّبِيُّ ﷺ قَالَ رُكَانَةُ وَسَمِعْتُ النَّبِيَّ ﷺ يَقُولُ فَرْقُ مَا بَيْنَنَا وَبَيْنَ الْمُشْرِكِينَ الْعَمَائِمُ عَلَى الْقَلاَنِسِ  

The Messenger of Allah ﷺ put a turban on me and let the ends hang in front of him and behind me.  

سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ يَقُولُ عَمَّمَنِي رَسُولُ اللَّهِ ﷺ فَسَدَلَهَا بَيْنَ يَدَىَّ وَمِنْ خَلْفِي
