And Allah the Exalted said: "But if you are prevented, then (offer) whatever sacrificial animal is available, and do not shave your heads (i.e., do not exit the state of Ihram) until the sacrificial animal reaches its place (i.e., until it is slaughtered in Mecca)." And Ata bin Abi Rabah, may Allah have mercy on him, said that whatever prevents (a person), the same ruling applies to it.

Narrated Nafi`: When `Abdullah bin `Umar set out for Mecca intending to perform Umra, at the time of afflictions, he said, "If I should be prevented from reaching the Ka`ba, then I would do the same as Allah's Apostle did, so I assume the lhram for Umra as Allah's Apostle assumed the Ihram for Umra in the year of Hudaibiya."

Narrated Nafi`: That Ubaidullah bin `Abdullah and Salim bin `Abdullah informed him that they told Ibn `Umar when Ibn Az-Zubair was attacked by the army, saying "There is no harm for you if you did not perform Hajj this year. We are afraid that you may be prevented from reaching the Ka`ba." Ibn `Umar said "We set out with Allah's Apostle and the non-believers of Quraish prevented us from reaching the Ka`ba, and so the Prophet slaughtered his Hadi and got his head shaved." Ibn `Umar added, "I make you witnesses that I have made `Umra obligatory for me. And, Allah willing, I will go and then if the way to Ka`ba is clear, I will perform the Tawaf, but if I am prevented from going to the Ka`ba then I will do the same as the Prophet did while I was in his company." Ibn `Umar then assumed Ihram for Umra from Dhul-Hulaifa and proceeded for a while and said, "The conditions of `Umra and Hajj are similar and I make you witnesses that I have made `Umra and Hajj obligatory for myself." So, he did not finish the Ihram till the day of Nahr (slaughtering) came, and he slaughtered his Hadi. He used to say, "I will not finish the Ihram till I perform the Tawaf, one Tawaf on the day of entering Mecca (i.e. of Safa and Marwa for both `Umra and Hajj).

Narrated Nafi`: Some of the sons of `Abdullah told him (i.e. `Abdullah) if he had stayed (and not performed Hajj that year).

Narrated Ibn `Abbas: Allah's Apostle was prevented from performing (`Umra) Therefore, he shaved his head and had sexual relations with his wives and slaughtered his Hadi and performed Umra in the following year.

Narrated Salim: (Abdullah) bin `Umar used to say, "Is not (the following of) the tradition of Allah's Apostle sufficient for you? If anyone of you is prevented from performing Hajj, he should perform the Tawaf of the Ka`ba and between As-Safa and Al-Marwa and then finish the Ihram and everything will become legal for him which was illegal for him (during the state of Ihram) and he can perform Hajj in a following year and he should slaughter a Hadi or fast in case he cannot afford the Hadi."

Narrated Al-Miswar: Allah's Apostle slaughtered (the Hadi) before he had his head shaved and then he ordered his Companions to do the same.

Narrated Nafi`: That `Abdullah and Salim said to `Abdullah bin `Umar, "(You should not go for Hajj this year)." `Abdullah bin `Umar replied, "We set out with the Prophet (to Mecca for performing `Umra) and e infidels of Quraish prevented us from reaching the Ka`ba. Allah's Apostle slaughtered his Budn (camels for sacrifice) and got his head shaved."

And Ruh said, from them Shibl bin ‘Iyad, from them Ibn Abi Najih, from them Mujahid, and from them Ibn ‘Abbas (may Allah be pleased with them both) that expiation (qada) becomes obligatory when someone, during Hajj, has intercourse with his wife and thereby breaks the intention of Hajj. But if some other excuse arises, or something else happens, then he becomes lawful (halal), and expiation is not necessary for him. And if he had a sacrificial animal with him and he was prevented (from reaching the Haram) and could not send it to the Haram, then he should slaughter it (wherever he is staying). This is in the case when he does not have the ability to send the sacrificial animal to the Haram, but if he has the ability, then he cannot exit the state of ihram until the sacrifice is slaughtered there. Imam Malik and others said that (the one prevented) should slaughter his sacrifice wherever he is, and shave his head, wherever he may be. Expiation is not obligatory upon him, because the Prophet (peace and blessings of Allah be upon him) and his companions (may Allah be pleased with them) at Hudaybiyyah, without performing tawaf and without reaching the House of Allah, slaughtered (their sacrifices) and shaved their heads, and they became lawful from everything. Then no one mentioned that the Prophet (peace and blessings of Allah be upon him) ordered anyone to make up (qada) or repeat anything, and Hudaybiyyah is outside the boundary of the Haram.

Narrated Nafi`: When `Abdullah bin `Umar set out for Mecca with the intentions performing `Umra in the period of afflictions, he said, "If I should be prevented from reaching the Ka`ba, then I would do the same as we did while in the company of Allah's Apostle ." So, he assumed the Ihram for `Umra since the Prophet had assumed the Ihram for `Umra in the year of Al-Hudaibiya. Then `Abdullah bin `Umar thought about it and said, "The conditions for both Hajj and `Umra are similar." He then turned towards his companions and said, "The conditions of both Hajj and `Umra are similar and I make you witnesses that I have made the performance of Hajj obligatory for myself along with `Umra." He then performed one Tawaf (between As-Safa and Al-Marwa) for both of them (i.e. Hajj and (`Umra) and considered that to be sufficient for him and offered a Hadi.
