She entered ihraam for ‘Umrah from Makkah and forgot one or two laps of saa’i

Firstly: 

If you entered ihraam for
‘Umrah from inside Makkah, and did not go out to a place beyond the
boundaries of the Haram, such as al-Tan’eem or what is called Masjid
‘Aa’ishah (the Mosque of Aa’ishah (may Allaah be pleased with her)), then
you failed to do one of the obligatory parts of ‘Umrah, namely entering
ihraam from the meeqaat. The meeqaat for ‘Umrah for the people of Makkah and
those who are staying there is the area outside the boundaries of the Haram,
so the one who is in Makkah and wants to do ‘Umrah must go out to any area
that is beyond the boundaries of the Haram and enter ihraam from there. If
he does not do that he must offer a sacrifice of a sheep to be slaughtered
and its meat to be distributed among the poor of the Haram. See the answer
to question no. 48955. 

Secondly: 

With regard to what you
have mentioned about omitting laps of saa’i, if it is only doubt or
conjecture that happened after you had finished saa’i, then it does not
matter, because doubt after finishing an act of worship does not affect it. 

Ibn Qaasim al-‘Aabidi said
in his commentary on Tuhfat al-Muhtaaj (4/81): If you are uncertain
about the number before you finish (the act of worship), then you must
proceed on the basis of the lower number, according to scholarly consensus.
If you think something different or are not sure of it afterwards, i.e.,
after finishing it, it does not matter. End quote. 

If you are certain that you
did a saa’i of six or five laps, then your saa’i was incomplete and your
exiting ihraam from ‘Umrah is not valid. One of the essential parts of
‘Umrah remains to be done, namely saa’i, and you are still in ihraam, and
you must do three things: 

1.Avoid all the things that are
forbidden whilst in ihraam, because you are still in your ihraam.

2.Go back to Makkah and do saa’i
from scratch.

3.Exit ihraam but cut a
fingertip’s length from your hair, because your first exiting ihraam took
place before the rituals had been completed, so it did not count.

Shaykh Ibn ‘Uthaymeen (may
Allaah have mercy on him) was asked about a man who did ‘Umrah but his saa’i
was one lap short. What must he do? 

He replied: 

This man is still in ihraam
and he must stop wearing ordinary clothes and avoid the things that are
forbidden whilst in ihraam, and he must immediately put on the ihraam
garments in the place where he is, and go to Makkah and do saa’i again,
because he is still in ‘Umrah now. End quote. 

Majmoo’ Fataawa
al-Shaykh Ibn ‘Uthaymeen (22/435). 

With regard to any
infractions of ihraam that you may have committed during this period, if
they were due to ignorance of the ruling, then you do not have to do
anything, but if they were done despite your knowing the ruling that you
were still in a state of ihraam, then you must offer a fidyah for them. 

See the answer to question
no. 36522. 

Thirdly: 

It is not prescribed for
you to enter ihraam for ‘Umrah from the meeqaat during your upcoming trip
(on Thursday), because you are still in a state of ihraam for your first
‘Umrah, as stated above. But if you reach Makkah and complete your first
‘Umrah then exit ihraam, then you want to do a second ‘Umrah, you should go
out to al-Tan’eem or anywhere that is beyond the boundaries of the Haram,
and enter ihraam for ‘Umrah. 

We ask Allaah to accept
(acts of worship) from us and from you. 

And Allaah knows best.
