Mishkat al-Masabih
Jabir said that God’s messenger entered on the day of the Conquest of Mecca wearing a black turban, but not wearing the ihram. Muslim transmitted it.
وَعَنْ جَابِرٍ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَ يَوْمَ فَتْحِ مَكَّةَ وَعَلَيْهِ عمامةٌ سوْداءُ بِغَيْر إِحْرَام. رَوَاهُ مُسلم
