It is narrated by Ya’la bin Umayyah that a man came to Prophet (ﷺ) at Ji’ranah, putting on ihram for ‘Umrah. He had a cloak on him and his beard and head had been dyed.
Sunan Abi Dawud Book 11, Hadith 102
← Previous Hadith This tradition has also been transmitted by Ya’la bin Umayyah through a different chain of narrators. This version adds The Apostle of Allaah(ﷺ) commanded him to take it off (the tunic) and to take a bath twice or thrice. The narrator then transmitted the rest of the tradition.

Sunan Abi Dawud Book 11, Hadith 101 Next Hadith → ‘Abd Allaah bin Umar said A man asked the Apostle of Allaah(ﷺ) What clothing one should put on if one intend to put on ihram? He said He should not wear shirts, turbans, trousers, garments with head coverings and clothing which has any dye of waras or saffron; one should not put on shoes unless one cannot get sandals. If one cannot get sandals, one should wear the shoes, in which case one must cut them to come below the ankles.
