Someone exited ihram of ‘umrah and shaved his head before doing sa‘i – what is the ruling?

Praise
be to Allah

Whoever does
that must do sa‘i, because it is an essential part of ‘umrah and cannot be
waived because one forgot to do it or was ignorant of it. Then after he has
done sa‘i, he must shave his head or cut his hair in order to exit his
ihram. The first time of shaving his head does not count, because it was
done at the wrong time. Shaving the head or cutting the hair in ‘umrah can
only come after doing tawaaf and sa‘i. With regard to what this person did
previously, when he exited his ihram and shaved his head before doing sa‘i,
he does not have to do anything, because he forgot, and the one who forgets
– and, likewise, the one who is ignorant – does not have to do anything with
regard to committing any of the acts that are prohibited whilst in ihram.

Shaykh Ibn
‘Uthaymeen was asked: I did ‘umrah and because I was sick I could not do
sa‘i. So I did tawaaf and prayed two rak‘ahs, and I exited ihram. Is my
‘umrah valid?

He (may Allah
have mercy on him) replied: This ‘umrah is not valid, because sa‘i is an
essential part of ‘umrah, so it must be done.

Therefore the
questioner must go now and put on the ihram garments, and do sa‘i between
as-Safa and al-Marwah, and cut his hair, because the first time he cut his
hair was done at the wrong time; or he may shave his head.

The individual
must not do anything that will affect his act of worship until after he has
asked people of knowledge, lest he do something that is a grave error
without realising. Acts of worship cannot be subjected to personal whims and
desires, omitting whatever one wants and limiting oneself whatever one
wants.

There are no
consequences that result from what the questioner did, because he was
ignorant of the ruling. Even if he had had intercourse with his wife when he
was ignorant of the ruling, there would be no blame on him. The same applies
to all the things that are prohibited whilst in ihram: if a person does them
out of ignorance, or because he forgot, or he did not do them deliberately,
as in the case of one who is forced to do something, then there is no sin on
him and he is not required to offer any expiation.
