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.
أَنَّ رَجُلاً أَتَى النَّبِيَّ ﷺ 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 ﷺ 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
