Sulaiman bin Yasar says: Sayyiduna Umar bin Khattab (may Allah be pleased with him) perceived the scent of perfume at Dhul-Hulaifah and asked: From whom is this fragrance coming? Sayyiduna Muawiyah (may Allah be pleased with him) said: O Commander of the Faithful! From me. Sayyiduna Umar (may Allah be pleased with him) said: By my life! It is coming from you. He said: Umm al-Mu'mineen Sayyidah Umm Habibah (may Allah be pleased with her) applied this perfume to me, and she believes that she also applied perfume to the Messenger of Allah (peace and blessings be upon him) at the time of donning Ihram. But Sayyiduna Umar (may Allah be pleased with him) said: Go and make her swear that she must wash it off in any case. Then he went to the lady and she washed it off.
