The Messenger of Allah ﷺ forbade the wearing of mufaddam.Yazid said, I asked al-Hasan, "What is mufaddam?"He replied, "Garments saturated with safflower dye."
حدثنا أبو بكر بن أبي شيبة حدثنا علي بن مسهر عن يزيد بن أبي زياد عن الحسن بن سهيل
نهى رسول الله ﷺ عن المفدم قال يزيد قلت للحسن ما المفدم قال المشبع بالعصفر
[Hasan] Ahmad reported it, 2/99, from the hadith of Yazid, as mentioned before, no. 504, and he explicitly stated hearing it. It is also in al-Musannaf, 8/182, and will come again, no. 3643. It has a corroborating witness in Nasai, 2/188, 189, with a hasan isnad, and it has other routes as well.
