Abu Dawud Book 4, Hadith Number 1815.
Chapter : Not known.
Narated By Ya’la ibn Umayyah : A man came to the Prophet (PBUH) when he was at al-Ji’ranah. He was wearing perfume or the mark of saffron was on him and he was wearing a tunic.
He said: Apostle of Allah, what do you command me to do while performing my Umrah. In the meantime, Allah, the Exalted, sent a revelation to the Prophet (PBUH).
When he (the Prophet) came to himself gradually, he asked: Where is the man who asking about umrah? (When the man came) he (the Prophet) said: Wash the perfume which is on you, or he said: (Wash) the mark of saffron (the narrator is doubtful), take off the tunic, then do in your umrah as you do in your hajj.
