Muhammad says that if a person makes Hajj obligatory upon himself and then is prevented (from completing it), he should send a sacrificial animal (hady). Then, when the sacrificial animal reaches its place, he will become lawful regarding some things and remain in the state of ihram regarding others. Then, when the next year comes, he should enter into ihram for both Hajj and Umrah, and if he combines both, then a sacrifice is also required of him. And if he wishes, when he is prevented, he may wait for a while, and when the prevention is lifted, he should go to the House of Allah and perform Umrah, and in the following year, perform only Umrah.

Hazrat Ibn Aun says that I asked Hazrat Salim and Hazrat Qasim about a person in the state of Ihsar. Both of them also gave the same answer as Muhammad.

Hazrat Ma'bad bin Hazabah al-Makhzumi had a seizure on the way during his journey to Makkah. His son went to the spring where his father had the seizure. On the way, he met Hazrat Ibn Abbas (may Allah be pleased with them), Hazrat Ibn Umar (may Allah be pleased with them), and Marwan bin Hakam. He mentioned his father's seizure to them. All of them said: He should use the medicine by which he gets well. Then, when he gets well, he should perform 'Umrah and thus complete his Hajj. And if he reaches the time of Hajj, he should perform Hajj and offer whatever sacrificial animal is available to him.
