Sahih Bukhari Volume 2, Book 25, Hadith 1537

قَالَ أَبُو عَاصِمٍ أَخْبَرَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي عَطَاءٌ، أَنَّ صَفْوَانَ بْنَ يَعْلَى، أَخْبَرَهُ أَنَّ يَعْلَى قَالَ لِعُمَرَ ـ رضى الله عنه ـ أَرِنِي النَّبِيَّ صلى الله عليه وسلم حِينَ يُوحَى إِلَيْهِ قَالَ فَبَيْنَمَا النَّبِيُّ صلى الله عليه وسلم بِالْجِعْرَانَةِ، وَمَعَهُ نَفَرٌ مِنْ أَصْحَابِهِ، جَاءَهُ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ كَيْفَ تَرَى فِي رَجُلٍ أَحْرَمَ بِعُمْرَةٍ، وَهْوَ مُتَضَمِّخٌ بِطِيبٍ فَسَكَتَ النَّبِيُّ صلى الله عليه وسلم سَاعَةً فَجَاءَهُ الْوَحْىُ، فَأَشَارَ عُمَرُ ـ رضى الله عنه ـ إِلَى يَعْلَى، فَجَاءَ يَعْلَى، وَعَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم ثَوْبٌ قَدْ أُظِلَّ بِهِ فَأَدْخَلَ رَأْسَهُ، فَإِذَا رَسُولُ اللَّهِ صلى الله عليه وسلم مُحْمَرُّ الْوَجْهِ، وَهُوَ يَغِطُّ ثُمَّ سُرِّيَ عَنْهُ فَقَالَ ‏"‏ أَيْنَ الَّذِي سَأَلَ عَنِ الْعُمْرَةِ ‏"‏ فَأُتِيَ بِرَجُلٍ فَقَالَ ‏"‏ اغْسِلِ الطِّيبَ الَّذِي بِكَ ثَلاَثَ مَرَّاتٍ، وَانْزِعْ عَنْكَ الْجُبَّةَ، وَاصْنَعْ فِي عُمْرَتِكَ كَمَا تَصْنَعُ فِي حَجَّتِكَ ‏"‏‏.‏ قُلْتُ لِعَطَاءٍ أَرَادَ الإِنْقَاءَ حِينَ أَمَرَهُ أَنْ يَغْسِلَ ثَلاَثَ مَرَّاتٍ قَالَ نَعَمْ‏

Narrated Safwan bin Ya'la:Ya'la said to Umar(R.A.),"Show me the Prophet (s.a.w.) when he is being inspired Divinely."While the Prophet(s.a.w.) was at Jirana(in company of some of his companions) a person came and asked,"O Allah's Messenger! What is your verdict regarding that person who assumes Ihram for Umra and is scented with perfume?"The Prophet (s.a.w.)kept quiet for a while and he was Divinely inspired (then).Umar beckoned Yala.So he came and Allah's Messenger(s.a.w.) was shaded with a sheet.Ya'la put his head in and saw that the face of Allah's messenger(s.a.w.) was red and he was snoring.when that state of the Prophet(s.a.w.) was over, he asked "Where is the person who asked about Umra?" Then that person was brought and the Prophet(s.a.w.) said,"Wash the perfume off your body thrice and take off the cloak and do the same in Umra as you do in Hajj."
