Is the reward of the one who performs Hajj alone the same as that of the one who combines it with 'Umrah and the one who performs them separately?

Question:
May Allah reward you and bless you. This questioner, Abu Faris, says: A man performed Hajj alone (ifrad) and fulfilled all his obligations in his obligatory Hajj, which was his first obligatory Hajj. Is his reward the same as the reward of the one who combines (qiran) and the one who performs them separately (tamattu'), even though he is poor?

Answer:
No, his reward is the reward of the one who performs Hajj alone, and he does not attain the reward of the one who combined Hajj and 'Umrah, whether by qiran or tamattu'. The one who performs tamattu' and the one who performs qiran have a more complete reward than the one who performs Hajj alone. As long as he has performed the obligatory Hajj, the 'Umrah remains a debt upon him. If he leaves after Hajj, going to al-Tan'im or to al-Hal, and enters the state of ihram for 'Umrah and performs it, it suffices for the 'Umrah of Islam. Yes.
