Sometimes such trouble harbours some big good which Allah knows best. All the members of the family, especially the younger sister, should recite after every salah and before going to bed Surah Quraish seven times with durood 7 times before and after. Moreover, they should keep on praying sincerely to Allah. May Allah ward off all troubles from you and provide you a pious perfect match for your sister. May Allah grant her bliss in this world and the world hereafter and grant her happy life.
Allah (Subhana Wa Ta’ala) knows Best
Darul Ifta,
Darul Uloom Deoband
