Sayyiduna Ya'la (may Allah be pleased with him) narrates that I was with the Prophet (peace and blessings of Allah be upon him) at Ji'ranah when a man came who was wearing a cloak and had applied perfume (khaluq). He said: O Messenger of Allah! I have entered into the state of Ihram for 'Umrah and these things (the cloak and perfume) are upon me, so what should I do? The Prophet (peace and blessings of Allah be upon him) asked: What do you do in your Hajj? He said: I remove this cloak and wash off the perfume. The Prophet (peace and blessings of Allah be upon him) said: Whatever you do in Hajj, do the same in 'Umrah.
