Yaala bin Umaya reported,

He used to say to Umar bin Khattab رضي الله عنه, "I wish I could see the Prophet of Allah ﷺ at the moment revelation descends upon him."When the Prophet ﷺ was at Jiranah, with a garment shading him from above and a group of his companions around him, including Umar, a man came to him wearing a woolen cloak smeared with perfume.The man asked, "Messenger of Allah, what do you say about a man who has entered the state of ihram for umrah while wearing a cloak after smearing himself with perfume?"The Prophet ﷺ looked at him for a while and remained silent. Then revelation came to him. Umar gestured with his hand to Yala bin Umaya, signaling, "Come."Yala came and put his head under the garment, and there was the Prophet ﷺ, his face flushed red, breathing heavily for a moment. Then it passed from him.He said, "Where is the one who asked me about umrah just now?"The man was sought out and brought to him. The Prophet ﷺ said, "As for the perfume on you, wash it off three times. As for the cloak, take it off. Then do in your umrah what you would do in your hajj."

Sahih

عن يعلى بن أمية

أنه كان يقول لعمر بن الخطاب رضي الله عنه ليتني أرى نبي الله ﷺ حين ينزل عليه، فلما كان النبي ﷺ بالجمرانة وعلى النبي ﷺ ثوب قد أظل به عليه معه ناس من أصحابه فيهم عمر، إذ جاءه رجل عليه جبة صوف متضمخ بطيب فقال: يا رسول الله، كيف ترى في رجل أحرم بعمرة في جبة بعد ما تضمخ بطيب؟ فنظر إليه النبي ﷺ ساعة ثم سكت، فجاءه الوحي فأشار عمر بيده إلى يعلى بن أمية: تعال فجاء يعلى فأدخل رأسه فإذا النبي ﷺ محمر الوجه يغط ساعة ثم سري عنه فقال: أين الذي سألني عن العمرة آنفا؟ فالتمس الرجل فجيء به فقال النبي ﷺ: أما الطيب الذي بك فاغسله ثلاث مرات، وأما الحبة فانزعها ثم اصنع في عمرتك ما تصنع في حجك.
