* She stipulated that in order to marry her he has to memorize Soorat al-Baqarah or Aal ‘Imraan or take her for Hajj

I want to know can memorization of Holy Quran or part of it be made
into a condition for marriage as one sister(she is a Hafiz) has put
this condition out to me to either memorize Surah al-Baqarah or Surah
ale-Imraan and her third option was Hajj after nikah. I can pick
either of the three. If I pick one of the first two what bothers me
then is I wouldn't be doing it for Allah swt it would be exclusively
to gain her hand. Please explain if this is allowed or not.

Praise be to Allaah.
If you want to marry her because she is religiously committed and you
agree to the condition, seeking thereby the pleasure of Allah and to
achieve this aim, and to marry someone who will help you to obey Allah
and you can help her, then there is nothing wrong with that and this
is part of striving for the Hereafter. Allah says (interpretation of
the meaning):
"And whoever desires the Hereafter and strives for it, with the
necessary effort due for it (i.e. does righteous deeds of Allaah's
obedience) while he is a believer (in the Oneness of AllaahIslâmic
Monotheism) — then such are the ones whose striving shall be
appreciated, (thanked and rewarded by Allaah)"
[al-Isra' 17:19].
Al-Nasaa'i (3340) narrated that Anas (may Allah be pleased with him)
said: Abu Talhah married Umm Sulaym and the dowry between them was
Islam; Umm Sulaym became Muslim before Abu Talhah. He proposed to her
and she said: I have become Muslim; if you become Muslim I will marry
you. So he became Muslim, and that was the dowry between them. Classed
as saheeh by al-Albaani inSaheeh al-Nasaa'i.
So strive to memorise the Holy Qur'aan as an act of worship and
obedience towards Allah, and seeking His reward and His pleasure.
There is no reason not to let the request of this sister be what
motivates you to do this act of worship, because it is not contrary to
sincerity. This is like those who enter some religious competitions
and let that a motive to memorise the Holy Qur'aan. So there is
nothing wrong with that and it is not contrary to sincerity.
The scholars of the Standing Committee for Issuing Fatwas were asked:
Taking part in religious competitions that offer cash prizes: are
these prizes halaal or haraam?
They replied: There is nothing wrong with accepting the prizes that
are donated by people in authority or other doers of good, because
that is encouragement to acquire knowledge and memorise the Book of
Allah, may He be glorified and exalted. In these and similar matters,
the believer should be sincere towards Allah and be happy to have
something that helps him in that, and his motivation should not be
only to get the money.
