كتاب الزينة من السنن
Read the English translation first, with the original Arabic directly underneath.
It was narrated that Zaid bin Aslam said:
"I saw Ibn 'Umar dyeing his beard yellow with Khaluq and I said: 'O Abu 'Abdur-Rahman, are you dyeing your beard yellow with Khaluq?' He said: 'I saw the Messenger of Allah [ﷺ] dyeing his beard yellow with it, and there was no other kind of dye that was dearer to him than this. He used to dye all of his clothes with it, even his 'Imamah (turban).'"
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا الدَّرَاوَرْدِيُّ، عَنْ زَيْدِ بْنِ أَسْلَمَ، قَالَ رَأَيْتُ ابْنَ عُمَرَ يُصَفِّرُ لِحْيَتَهُ بِالْخَلُوقِ فَقُلْتُ يَا أَبَا عَبْدِ الرَّحْمَنِ إِنَّكَ تُصَفِّرُ لِحْيَتَكَ بِالْخَلُوقِ . قَالَ إِنِّي رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يُصَفِّرُ بِهَا لِحْيَتَهُ وَلَمْ يَكُنْ شَىْءٌ مِنَ الصِّبْغِ أَحَبَّ إِلَيْهِ مِنْهَا وَلَقَدْ كَانَ يَصْبُغُ بِهَا ثِيَابَهُ كُلَّهَا حَتَّى عِمَامَتَهُ . قَالَ أَبُو عَبْدِ الرَّحْمَنِ وَهَذَا أَوْلَى بِالصَّوَابِ مِنْ حَدِيثِ قُتَيْبَةَ .
