When Abdullah bin Umar (may Allah be pleased with them both) set out towards Makkah with the intention of Umrah in the year when there was turmoil (that is, when Hajjaj bin Yusuf came to fight Abdullah bin Zubair, may Allah be pleased with him, who was the ruler of Makkah), he said: If I am prevented from reaching the House of Allah, I will do as I did with the Messenger of Allah (peace and blessings be upon him) (when the disbelievers prevented him). So Abdullah bin Umar (may Allah be pleased with them both) entered into the state of Ihram for Umrah, thinking that the Messenger of Allah (peace and blessings be upon him) had also entered into Ihram for Umrah in the year of Hudaybiyyah. Then Abdullah bin Umar (may Allah be pleased with them both) reflected and said that the ruling of Umrah and Hajj is the same in the state of being prevented (ihsar). Then he turned to his companions and said that the case of Hajj and Umrah is the same. I make you witnesses that I have made Hajj obligatory upon myself along with Umrah. Then Abdullah (may Allah be pleased with him) went on until he reached the House of Allah, performed one Tawaf, considered it sufficient, and sacrificed the Hady.

Imam Malik, may Allah have mercy on him, said: In our view, the ruling for one who is prevented (from Hajj or Umrah) due to an enemy is the same as what the Prophet, peace be upon him, and his companions did.

Imam Malik, may Allah have mercy on him, said: Whoever is prevented for any reason other than an enemy will not become halal (released from ihram) except after reaching the House of Allah.
