A man came to the Prophet ﷺ while he was at al-Jiranah, with traces of perfume on him, or he said yellow stain, and wearing a long cloak. He said, "Messenger of Allah, what do you command me to do regarding my Umra?"Then Allah sent down revelation upon the Prophet ﷺ. When it had passed, he asked, "Where is the man who asked about the Umra?"He said, "Wash off the traces of perfume from yourself," or he said, "the traces of yellow stain, take off the cloak, and do in your Umra what you do in your Hajj."

أن رجلا أتى النبي ﷺ وهو بالجعرانة وعليه أثر خلوق أو قال صفرة وعليه جبة فقال يا رسول الله كيف تأمرني أن أصنع في عمرتي فأنزل الله تبارك وتعالى على النبي ﷺ الوحي فلما سري عنه قال أين السائل عن العمرة قال اغسل عنك أثر الخلوق أو قال أثر الصفرة واخلع الجبة عنك واصنع في عمرتك ما صنعت في حجتك
