A man came to the Prophet ﷺ having entered the state of ihram for umrah, wearing stitched garments and smeared with perfume. He asked, "I have entered ihram for umrah, so what should I do?"The Prophet ﷺ asked, "What would you have done in your hajj?"The man replied, "I would have avoided this perfume and washed it off, and removed these garments."The Prophet ﷺ said, "Whatever you would have done in your hajj, do the same in your umrah."
