باب مَا يُبَاحُ لِلْمُحْرِمِ بِحَجٍّ أَوْ عُمْرَةٍ وَمَا لاَ يُبَاحُ وَبَيَانِ تَحْرِيمِ الطِّيبِ عَلَيْهِ
Sahih Muslim 1180 a

Ya'la b. Umayya reported on the authority of his father (Allah be pleased with them) that a person came to the Messenger of Allah (ﷺ) as he was at Ji'rana and he (the person) had been putting on a cloak which was perfumed, or he (the narrator) said:

There was a trace of yellowness on it. He said (to the Holy Prophet): What do you command me to do during my Umra? (It was at this juncture) that the revelation came to the Messenger of Allah (ﷺ) and he was covered with a cloth, and Ya'la said: Would that I see revelation coming to the Messenger of Allah (ﷺ). He (Hadrat 'Umar) said: Would it please you to see the Messenger of Allah (ﷺ) receiving the revelations 'Umar lifted a corner of the cloth and I looked at him and he was emitting a sound of snorting. He (the narrator) said: I thought it was the sound of a camel. When he was relieved of this he said: Where is he who asked about Umra? When the person came, the Prophet (ﷺ) said: Wash out the trace of yellowness, or he said: the trace of perfume and put off the cloak and do in your 'Umra what you do in your Hajj.
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا عَطَاءُ بْنُ أَبِي رَبَاحٍ، عَنْ صَفْوَانَ، بْنِ يَعْلَى بْنِ أُمَيَّةَ عَنْ أَبِيهِ، - رضى الله عنه - قَالَ جَاءَ رَجُلٌ إِلَى النَّبِيِّ صلى الله عليه وسلم وَهُوَ بِالْجِعْرَانَةِ عَلَيْهِ جُبَّةٌ وَعَلَيْهَا خَلُوقٌ - أَوْ قَالَ أَثَرُ صُفْرَةٍ - فَقَالَ كَيْفَ تَأْمُرُنِي أَنْ أَصْنَعَ فِي عُمْرَتِي قَالَ وَأُنْزِلَ عَلَى النَّبِيِّ صلى الله عليه وسلم الْوَحْىُ فَسُتِرَ بِثَوْبٍ وَكَانَ يَعْلَى يَقُولُ وَدِدْتُ أَنِّي أَرَى النَّبِيَّ صلى الله عليه وسلم وَقَدْ نَزَلَ عَلَيْهِ الْوَحْىُ - قَالَ - فَقَالَ أَيَسُرُّكَ أَنْ تَنْظُرَ إِلَى النَّبِيِّ صلى الله عليه وسلم وَقَدْ أُنْزِلَ عَلَيْهِ الْوَحْىُ قَالَ فَرَفَعَ عُمَرُ طَرَفَ الثَّوْبِ فَنَظَرْتُ إِلَيْهِ لَهُ غَطِيطٌ - قَالَ وَأَحْسِبُهُ قَالَ - كَغَطِيطِ الْبَكْرِ - قَالَ - فَلَمَّا سُرِّيَ عَنْهُ قَالَ ‏ "‏ أَيْنَ السَّائِلُ عَنِ الْعُمْرَةِ اغْسِلْ عَنْكَ أَثَرَ الصُّفْرَةِ - أَوْ قَالَ أَثَرَ الْخَلُوقِ - وَاخْلَعْ عَنْكَ جُبَّتَكَ وَاصْنَعْ فِي عُمْرَتِكَ مَا أَنْتَ صَانِعٌ فِي حَجِّكَ ‏"‏ ‏.‏
