Ya‘la b. Umayya (Umayya was Ya'la’s mother) said

When we were with the Prophet (ﷺ) at al- Ji'rana a desert Arab came to him wearing a tunic which was copiously perfumed (Literally “smeared copiously with khaluq." This is a perfume composed of saffron and other elements, yellow and red being the predominant colours) and said, “ Messenger of Allah , I entered the sacred state for the ’umra while wearing this.” He replied, “Wash the perfume which is on you three times, take off the tunic, then do in your ’umra as you do in your hajj.” Bukhari and Muslim.
