Sunan Ibn Majah Book 25, Hadith 96
“The Messenger of
Allah
(ﷺ) stood up to deliver a speech in this valley, and said:
‘Lo!
‘Umrah has been included in Hajj until the Day of Resurrection.”
I heard the Messenger of Allah (ﷺ) say, when he was in ‘Aqiq: “Someone came to me from my Lord and said: ‘Pray in this blessed valley and say: (I intend to do) ‘Umrah in Hajj.’”
“Imran bin Husain said to me: ‘I will tell you a Hadith, that Allah may benefit you thereby after this day. Know that Allah’s Messenger (ﷺ) had a group from his family perform ‘Umrah during the ten (days) of Dhul-Hijjah, and the Messenger of Allah (ﷺ) did not forbid that, and no abrogation of that was revealed, and it does not matter what anyone else suggests.’”
