He lost his Money and he was not able to sacrifice an Animal, so he changed his Hajj to Hajjul-Ifrad
Question :
What is the ruling on whoever assumed Ihram for Hajj and 'Umrah, and after his arrival in Makkah he lost his spending money and was not able to sacrifice an animal and he changed his intention to a Mufrid? Is this correct? If the Hajj was for someone else who stipulated that he must perform Hajjut-Tamattu', what should he do?
Answer:
He may not do that, even if he lost his spending money. If he is not able to perform the sacrifice, he fasts ten days - and all praise is due to Allâh. He fasts three days during the Hajj and seven days when he returns to his people (i.e., his land), and he remains a Mutamatti'. He must carry out the condition by assuming Ikram for 'Umrah, performing Tawaf and Say, getting his hair cut and removing his Ihram. Then, he says the Talbiyyah for Hajj (on the 8th) and he sacrifices an animal (on the 10th). If he is not able to perform the sacrifice, he fasts ten days - three days during Hajj, before 'Arafah, and seven days when he returns to his family. This is because it is better that he do not fast on the day of 'Arafah following the Prophet's Sunnah. For verily, he (the Prophet) stood at 'Arafat while not fasting.
