How can one regain patience in supplicating and entreating for something for which there are no signs of a response, especially after years of continuous supplication?

It is recommended to have piety, patience, and certainty that relief comes with hardship. The questioner should move to a country with a large Muslim population to increase her chances of marriage, and not worry about something that is predestined, for only what Allah has allotted for her will come to her. Supplication is a mighty weapon, so she should supplicate with certainty of being answered, choose virtuous times, ensure her food and drink are pure, and be wary of hastening the answer. The Prophet (peace be upon him) said: "The supplication of anyone of you is granted as long as he does not show impatience by saying: 'I supplicated but I was not granted my supplication.'" Supplication is stored for the servant. The Messenger of Allah (peace be upon him) said: "No man supplicates to Allah with a supplication except that he is answered, either it is hastened for him in this world, or it is stored for him in the Hereafter... as long as he does not supplicate for a sin or cutting off ties of kinship, or hasten it." If she dies chaste, she will have a great reward, and what she missed in this world will not be missed in Paradise if she remains steadfast upon the truth. There is no impediment for her to express her desire to some of her Muslim sisters so that they may strive to find a righteous husband for her.
