Mukhtasar Muslim

Narrated from Nafi‘ that Abdullah bin Umar (may Allah be pleased with them both) set out for ‘Umrah during the days of tribulation and said: If I am prevented from reaching the House of Allah, I will do as we did with the Messenger of Allah (peace and blessings be upon him). Then he assumed the Ihram for ‘Umrah and set out until he reached (the place) Bida’, (where most of the Companions heard the Talbiyah of the Messenger of Allah (peace and blessings be upon him) during the Farewell Hajj). He said to his companions: The ruling of Hajj and ‘Umrah is the same, that both can be entered into with Ihram. So I make you witnesses that I have made Hajj obligatory upon myself along with ‘Umrah. Then he proceeded until he reached the House of Allah, performed seven circuits of Tawaf, and made Sa‘i between Safa and Marwah seven times. He did nothing more than this and considered it sufficient, and he offered a sacrifice.
