Mishkat al-Masabih 2680
Ya‘la b. Umayya (Umayya was Ya'la’s mother) said:
When we were with the Prophet 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 God, 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.
وَعَنْ يَعْلَى بْنِ أُمَيَّةَ قَالَ: كُنَّا عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بالجعرانة إِذْ جَاءَ رَجُلٌ أَعْرَابِيٌّ عَلَيْهِ جُبَّةٌ وَهُوَ مُتَضَمِّخٌ بِالْخَلُوقِ فَقَالَ: يَا رَسُولَ اللَّهِ إِنِّي أَحْرَمْتُ بِالْعُمْرَةِ وَهَذِهِ عَلَيَّ. فَقَالَ: «أَمَا الطِّيبُ الَّذِي بِكَ فَاغْسِلْهُ ثَلَاثَ مَرَّاتٍ وَأَمَّا الْجُبَّةُ فَانْزِعْهَا ثُمَّ اصْنَعْ فِي عُمْرَتِكَ كَمَا تَصْنَعُ فِي حَجِّكَ»
