Narrated Ya'la ibn Umayyah:
A man came to the Prophet (ﷺ) when he was at al-Ji'ranah. He was wearing perfume or the mark of saffron was on him and he was wearing a tunic. He said: Messenger of Allah, what do you command me to do while performing my Umrah. In the meantime, Allah, the Exalted, sent a revelation to the Prophet (ﷺ). When he (the Prophet) came to himself gradually, he asked: Where is the man who asking about umrah? (When the man came) he (the Prophet) said: Wash the perfume which is on you, or he said: (Wash) the mark of saffron (the narrator is doubtful), take off the tunic, then do in your umrah as you do in your hajj.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا هَمَّامٌ، قَالَ سَمِعْتُ عَطَاءً، أَخْبَرَنَا صَفْوَانُ بْنُ يَعْلَى بْنِ أُمَيَّةَ، عَنْ أَبِيهِ، أَنَّ رَجُلاً، أَتَى النَّبِيَّ صلى الله عليه وسلم وَهُوَ بِالْجِعْرَانَةِ وَعَلَيْهِ أَثَرُ خَلُوقٍ - أَوْ قَالَ صُفْرَةٍ - وَعَلَيْهِ جُبَّةٌ فَقَالَ يَا رَسُولَ اللَّهِ كَيْفَ تَأْمُرُنِي أَنْ أَصْنَعَ فِي عُمْرَتِي فَأَنْزَلَ اللَّهُ تَبَارَكَ وَتَعَالَى عَلَى النَّبِيِّ صلى الله عليه وسلم الْوَحْىَ فَلَمَّا سُرِّيَ عَنْهُ قَالَ " أَيْنَ السَّائِلُ عَنِ الْعُمْرَةِ " . قَالَ " اغْسِلْ عَنْكَ أَثَرَ الْخَلُوقِ - أَوْ قَالَ أَثَرَ الصُّفْرَةِ - وَاخْلَعِ الْجُبَّةَ عَنْكَ وَاصْنَعْ فِي عُمْرَتِكَ مَا صَنَعْتَ فِي حَجَّتِكَ " .
