Sunan an-Nasa'i, Volume 3, Book 24, Hadith 2710 (DarusSalam) ⓘ

It was narrated from Safwan bin Ya'la, from his father, that: a man came to the Prophet who had initiated Ihram for 'Umrah, wearing sewn garments and having put on Khaluq. He said: "I have initiated Ihram for 'Umrah, so what should I do?" The Prophet said: "What would you do if you were doing Hajj?" He said: "I would avoid this and wash it off." He said: "Whatever you would do for Hajj, do it, for 'Umrah," (sahih)

أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ عَطَاءٍ، عَنْ صَفْوَانَ بْنِ يَعْلَى، عَنْ أَبِيهِ، أَنَّ رَجُلاً، أَتَى النَّبِيَّ صلى الله عليه وسلم وَقَدْ أَهَلَّ بِعُمْرَةٍ وَعَلَيْهِ مُقَطَّعَاتٌ وَهُوَ مُتَضَمِّخٌ بِخَلُوقٍ فَقَالَ أَهْلَلْتُ بِعُمْرَةٍ فَمَا أَصْنَعُ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ مَا كُنْتَ صَانِعًا فِي حَجِّكَ ‏"‏ ‏.‏ قَالَ كُنْتُ أَتَّقِي هَذَا وَأَغْسِلُهُ ‏.‏ فَقَالَ ‏"‏ مَا كُنْتَ صَانِعًا فِي حَجِّكَ فَاصْنَعْهُ فِي عُمْرَتِكَ ‏"‏ ‏.‏
