Respected hakeem sahib, Asslamo alikom! My sister got engaged somewhere, there was a big difference in age and also had a loose character. I started some spiritual remedies for a good proposal. I used to go in a masjid, clean it and perform two units of voluntary salah for her need and besides also used to recite surah Fateha 41 times between sunnah and farz of fajar salah and after it used to invoke also. My sister's engagement broke up there and she got engaged to a man who was pious and punctual in Salah and she is very happy there now. (Muhammad Asad, Peshawer).
