The ruling on one who performs Hajj on behalf of another as an ifrad pilgrim, having been conditioned to perform it as a tamattu' pilgrim

The questioner:
A man says: I took a sum of money from another man to perform Hajj on behalf of his father as a substitute, as a tamattu' pilgrim, but I performed it for him as an ifrad pilgrim because I was in Makkah, and then I performed 'Umrah for him. What is the ruling on that, knowing that this pilgrim does not know him, because he went to his country?

The Shaykh:
We repeat the question.

The Shaykh:
He made a mistake in this and they conditioned him to perform Hajj as a tamattu' pilgrim, and tamattu' is the best of the types of Hajj. His performing it as an ifrad pilgrim is contrary to the condition, so he erred in that. However, since he performed the 'Umrah afterwards, we hope that his liability is cleared, because the person on whose behalf it was performed received both Hajj and 'Umrah. But he commits a sin by violating the condition. Yes.
