وَعَنْ جَابِرٍ رضى اللَّه عَنْهُ ، أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ دَخَلَ يَوْمَ فَتْحِ مَكَّةَ وَعَلَيْهِ عِمَامَةٌ سَوْدَاءُ.((رَوَاهُ مُسْلِم))
Jabir (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) entered Makkah on the day of its conquest and he was wearing a black turban. [Muslim].
