I saw Ibn Umar dyeing his beard yellow with khaluq, so I said, "Abu Abdul-Rahman, you dye your beard yellow with khaluq?"He replied, "I saw the Messenger of Allah ﷺ dye his beard yellow with it, and no dye was more beloved to him than this. He used to dye all of his garments with it, even his turban."Abu Abdul-Rahman said, this is more likely correct than the hadith of Qutayba.
أخبرنا يعقوب بن إبراهيم قال حدثنا الدراوردي
رأيت ابن عمر يصفر لحيته بالخلوق فقلت يا أبا عبد الرحمن إنك تصفر لحيتك بالخلوق قال إني رأيت رسول الله ﷺ يصفر بها لحيته ولم يكن شيء من الصبغ أحب إليه منها ولقد كان يصبغ بها ثيابه كلها حتى عمامته قال أبو عبد الرحمن وهذا أولى بالصواب من حديث قتيبة
[Its chain of transmission is sahih] Abu Dawud narrated it in the Book of Clothing, Chapter on Yellow-Dyed Garments, no. 4064, from the hadith of Abdul-Aziz bin Muhammad Darawardi through the same route, and it is also in al-Kubra, no. 9358.
