What is the supplication that will facilitate the marriage of a girl who is complaining about her family and bring her a righteous husband quickly, especially since she was engaged to her cousin and divorced by her own will, and is being taunted by her family?

Late marriage does not mean it will not happen, and the departure of some suitors might contain good. You should supplicate frequently and take the necessary means, as explained in fatwas 71066 and 73988. Your family should not reproach you for this; rather, they should be a support for you. We advise reviewing fatwas 81754 and 73988. We ask Allah to ease your affairs and grant you a righteous husband.
