Grand Ayatollah Wahid Khorasani answers a question on marriage:
Suitor for a girl
Question: I am a single girl who has not been approached even by a single suitor, in spite of having a good family and observing Hijab thoroughly. Due to this I have been teased by strangers, acquaintances and even my own brothers. I am in extreme torment and agony on account of this issue, I have done Tawassul (intersession) to the Imams, recited Ziarat-e-Ashura and Salaatul-Haajaat, but I have not achieved any results yet, please guide me.
Answer: Probably prayers have been granted, but their moment of fulfillment is in the future, do not give up hope (و لا تقنطوا من رحمة الله).
Your prayers, Ziarat-e-Ashura and the said acts are all effective and rewarded for, and with God’s grace a suitable husband will come your way, stay hopeful to God the Exalted and continue doing Tawassul to the Ahlul Bayt (A.S) and stay mindful of your duties towards the wajibats (obligations) and muharramat (forbiddenl) to prevent negligence.
In addition, perform the following Tawassul:
Pray two Raka’at Sala’at like morning prayer, after prayer, recite the tasbeeh of Hazrat Zahra (S.A.), then it is better to go into prostration and recite Salawaat 14 times and ) (الّلهمّ خـِرْ لي و اخْتَرْ لي100 times, followed by 100 Salawaats. God willing your prayers will be granted soon.
