It is narrated from Hazrat Aslam, who was the freed slave of Sayyiduna Umar bin Khattab (may Allah be pleased with him), that Sayyiduna Umar bin Khattab (may Allah be pleased with him) smelled fragrance while he was at Shajarah (which is six miles from Madinah), so he asked, "From whom is this fragrance coming?" Sayyiduna Muawiyah bin Abi Sufyan (may Allah be pleased with him) replied, "From me, O Commander of the Faithful!" Sayyiduna Umar (may Allah be pleased with him) said, "Yes, I ask you by Allah, the Everlasting." Sayyiduna Muawiyah (may Allah be pleased with him) said, "Umm al-Mu'mineen Sayyidah Umm Habibah (may Allah be pleased with her) applied the fragrance on me, O Commander of the Faithful!" Sayyiduna Umar (may Allah be pleased with him) said, "I ask you to go and wash it off."
