Sahih Muslim , Book 43, Hadith 131 (In-Book) ⓘ
Ibn Sirin reported: Anas b. Malik was asked whether Allah's Messenger dyed his hair. He said: He had not become old enough to have white hair. Ibn Idris said that he had a few white hair. Abu Bakr and Umar, however, dyed hair with hina' (henna).
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ وَعَمْرٌو النَّاقِدُ جَمِيعًا عَنِ ابْنِ إِدْرِيسَ، - قَالَ عَمْرٌو حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ الأَوْدِيُّ، - عَنْ هِشَامٍ، عَنِ ابْنِ سِيرِينَ، قَالَ سُئِلَ أَنَسُ بْنُ مَالِكٍ هَلْ خَضَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم قَالَ إِنَّهُ لَمْ يَكُنْ رَأَى مِنَ الشَّيْبِ إِلاَّ - قَالَ ابْنُ إِدْرِيسَ كَأَنَّهُ يُقَلِّلُهُ - وَقَدْ خَضَبَ أَبُو بَكْرٍ وَعُمَرُ بِالْحِنَّاءِ وَالْكَتَمِ .
