"‏ أَيْنَ السَّائِلُ عَنِ الْعُمْرَةِ اغْسِلْ عَنْكَ أَثَرَ الصُّفْرَةِ - أَوْ قَالَ أَثَرَ الْخَلُوقِ - وَاخْلَعْ عَنْكَ جُبَّتَكَ وَاصْنَعْ فِي عُمْرَتِكَ مَا أَنْتَ صَانِعٌ فِي حَجِّكَ ‏"

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.
