He did not complete the tawaaf of ‘Umrah and he is doing Hajj tamattu’

Tawaaf is one of the essential pillars of ‘Umrah, which is
not valid without it. The tawaaf which counts for ‘umrah is seven circuits,
starting and ending at the Black Stone, because the Prophet (peace and
blessings of Allaah be upon him) did tawaaf in this manner, and he said:
“Learn from me your rituals (of pilgrimage).” 

Al-Nawawi (may Allaah have mercy on him) said: The condition
of tawaaf is that it should be seven circuits, each starting and ending at
the Black Stone. If one circuit of the seven is omitted, his tawaaf does not
count, whether he stays in Makkah or leaves and goes back to his country,
and that cannot be atoned for by offering a sacrifice or by anything else.
Al-Majmoo’, 8/21. 

Based on that, his ‘umrah was not complete, and he did not
exit from ihraam for it, and what he did of exiting ihraam and having
intercourse with his wife are forbidden actions that he did when he was
still in ihraam for ‘umrah. But he did those forbidden actions thinking that
he had finished his ‘umrah and exited from ihraam for it. Hence he does not
have to offer any fidyah for these actions. See question no.

Moreover this man entered ihraam for Hajj on the basis that he was doing
Hajj tamattu’, but in fact he had not completed his ‘umrah, so he joined
Hajj to ‘umrah, thus in effect he was doing Hajj qiraan. Shaykh Ibn
‘Uthaymeen (may Allaah have mercy on him) was asked about a man who did Hajj
tamattu’ and he did an incomplete tawaaf, i.e., only four circuits, then he
did saa’i and cut his hair, and he had intercourse with his wife, and then
he completed his Hajj. 

He replied: 

In effect he has done Hajj qiraan, because he joined Hajj to
‘umrah before tawaaf, because his first tawaaf was faulty. Joining Hajj to
‘umrah means that one is doing Hajj qiraan. There remains the issue of his
having exited ihraam, put on ordinary clothes and had intercourse, but he
was ignorant, so he does not have to do anything (i.e., offer a fidyah).
Based on this, his Hajj is complete, but it was Hajj qiraan, not Hajj
tamattu’.
