All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
The Prophet loved wearing white clothes and urged people to do so. Ibn ‘Abbaas narrated that the Prophet said: “Wear white clothes as they are from the best of your clothes, and enshroud your dead in them.” [Abu Daawood, At-Tirmithi and Ibn Maajah]
However, the Prophet did not restrict himself to wearing a particular color of clothes; rather, he used to wear whatever was available. It was reported that he wore a black turban. ‘Amr Ibn Hurayth narrated that the Prophet preached to the people while wearing a black turban on his head; for more on this, please refer to Fatwas 84272 and 86786.
He also wore a yellow turban. Al-Fadhl Ibn ‘Abbaas who entered upon the Prophet at the time of his death–sickness, said, “He wore a yellow turban on his head, and I greeted him with Salaam…”
Allaah Knows best.
