Makhul (may Allah have mercy on him) said: A woman came to the Messenger of Allah (peace and blessings be upon him) with a garment dyed yellow and said: O Messenger of Allah (peace and blessings be upon him)! I intend to perform Hajj; may I enter ihram in this? He (peace and blessings be upon him) said: "Do you have any garment other than this?" She said: No. He (peace and blessings be upon him) said: "Then enter ihram in it."
