I'm 29 yrs old divorced muslim women, my first marriage was a an intercaste marriage, I am searching for proposals for second marriage for past 2 yrs, but I am not able to get a suitable marriage, all proposals are getting denied for any reason, so please suggest me a dua or surah which will help me getting married soon.

If you sometimes pray in the mosque, then du`a between the two prayer-calls is never rejected. That`s how I found my wife actually. Also if you can ask your parents to pray for you, Allaah will undoubtedly respond to their request. Try to read Surat Jasin often, especially in the morning, because by it Allaah will make easy any affair in shaa Allaah. This is what I know of advive from Sunnah, and Allaah knows best. And when you pray for dunja, then never forget to look ahead , and pray also for your Deen and your akhirah. And be patient for your Lord. And don`t jump to proposals, but make always solaah al-istikharah, and trust Allaah. Best wishes. Take care. May Allaah guide you, console you, give you a righteous husband and children and make you good to them, and protect you all upon Serat Al-Mustaqiim. Aamiin. Salaam.
