حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ لَيْثٍ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ جِيءَ بِأَبِي قُحَافَةَ يَوْمَ الْفَتْحِ إِلَى النَّبِيِّ ـ صلى الله عليه وسلم ـ وَكَأَنَّ رَأْسَهُ ثَغَامَةٌ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " اذْهَبُوا بِهِ إِلَى بَعْضِ نِسَائِهِ فَلْتُغَيِّرْهُ وَجَنِّبُوهُ السَّوَادَ " .
It was narrated from Jabir that he said: “Abu Quhaifah was brought to the Prophet (ﷺ) on the Day of the Conquest (of Makkah), and his head was all white. The Messenger of Allah (ﷺ) said: ‘Take him to some of his womenfolk and let them change this, but avoid black.’”
