Sa'd bin Ibrahim سعد بن إبراهيم بن عبد الرحمن · The Book on Clothing

From his father that Rukanah wrestled the Prophet (ﷺ) and the Prophet (ﷺ) won the match. Rukanah said: "I heard the Messenger of Allah (ﷺ) saying: 'Indeed what distinguishes between us and between the idolater is the turban over the cap.'" This Hadith is Hasan Gharib. Its chain is not established, and we do not know of Abu Al-Hasan Al-'Asqalani, nor Ibn Rukanah.
