Safwan bin Ya'la narrates from his father: I said to Sayyiduna Umar bin Khattab (may Allah be pleased with him): I wish to see the Messenger of Allah (peace and blessings be upon him) at the time when revelation is being sent down upon him. Sayyiduna Ya'la (may Allah be pleased with him) says: We were present at the place of "Ji'ranah." Sayyiduna Umar (may Allah be pleased with him) called me. I came to him, and at that time a sheet had been placed over the Messenger of Allah (peace and blessings be upon him). Sayyiduna Umar (may Allah be pleased with him) removed the cloth from the face of the Messenger of Allah (peace and blessings be upon him) and showed me, and the blessed face of the Prophet (peace and blessings be upon him) was turning red. When this state of the Messenger of Allah (peace and blessings be upon him) ended, he said: Where is the questioner? Before this, a man had come to the Messenger of Allah (peace and blessings be upon him). He was drenched in perfume and had worn a sewn garment to enter into Ihram. (Sayyiduna Ya'la (may Allah be pleased with him) narrates) That questioner said: Here I am. The Messenger of Allah (peace and blessings be upon him) said: "What would you do in your Hajj?" He replied: I would wash off the perfume and remove the sewn garment (jubba). The Messenger of Allah (peace and blessings be upon him) said: "Do in your Umrah what you do in your Hajj."
