Du’aa, in essence, refers to that which emanates from the heart. Hence, one may ask from the bottom of his heart in whichever language he may desire. Allah Ta’ala, who is the fulfiller of all needs, is All-Hearing and All-Understanding. However, you may read the Du’aa, ?Rabb Inniy lima anzalta ilayya min khayrin faqeer?. Also, recite Salaatul Haajat and make Istikhaara.
We would like to emphasise that boyfriend/girlfriend relationship is totally un-Islamic and is nothing but Zina (adultery). Hence, we advise that all the relevant parties meet as soon as possible and get the marriage done.
and Allah Ta’ala Knows Best
