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 ‏"‏ ‏.‏

Narrated Ya'la ibn Umayyah: A man came to the Prophet (PBUH) 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 (PBUH). 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.
