What is the ruling on changing the intention in Hajj from ifrad to tamattu'?

Question:
This questioner asks, saying: At the miqat, I intended to perform Hajj as ifrad, and when I arrived in Makkah, I performed tawaf around the House. But now it is difficult for me to remain in the clothes of ihram. Is it permissible for me to change the previous intention to the intention of tamattu'?

Answer:
Yes, and this is better. Changing from ifrad to tamattu' is better. So you must complete the 'Umrah. You have now performed tawaf around the House, so you must perform sa'y for the 'Umrah and shorten your hair. By doing so, you come out of your ihram. When the day of the eighth comes, you enter the state of ihram for Hajj, and you owe the fidyah of tamattu', because you must slaughter a sheep, or take a seventh of a camel, or a seventh of a cow. If you are unable to slaughter, you must fast three days during Hajj and seven days when you return to your country and your family. Yes.
