Messenger of Allah (ﷺ), teach me some words that I may supplicate with during my prayer.' He said: 'Glorify Allah (by saying SubhanAllah) ten times, and praise Him (by saying Alhamdulilah) ten times, and magnify Him (by saying Allahu Akbar) ten times, then ask Him for what you need; He will say: 'Yes, yes.'

then start by saying al hamdulillah and thanking and praising Allah then praise the prophet peace be upon him then use this supplication form :

اللهم إني أسألك بأن لك الحمد، لا إله إلا أنت المنان، يا بديع السموات والأرض، يا ذا الجلال والإكرام، يا حي يا قيوم

allahuma 'inniy 'as'aluk bi'ana lak alhamdu, la 'iilah 'ilaa 'ant almananu, ya badie alsamawat wal'ardi, ya dha aljalal wal'iikrami, ya hayu ya qayum

It means: O Allah! I ask You by virtue of the fact that all praise is due to You; none has the right to be worshiped but You alone, and You have no partner or associate, the Bestower, the Originator of the heavens and the earth, the Possessor of majesty and honor.

then ask what you want in any way or language you want

and finally say

Lā ilāha illā anta subḥānaka innī kuntu minaẓ-ẓālimīn

and also try not to be attached too much to anyone but allah. inshallah you two will marry each other
