All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
We ask Allah, The Almighty, to bless you with a righteous husband who would make you happy and help you in your worldly and religious affairs, and to bless you with righteous offspring. We advise you to supplicate Allah, The Exalted, frequently and entrust your affairs to Him; you do not know what is really good for you, and Allah, The Exalted, knows all what is hidden in the hearts and the consequences of all matters. Therefore, do not despair if you failed to marry the man you wished to marry; Allah, The Almighty, Says (what means): {But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah Knows, while you know not.} [Quran 2:216]
Therefore, we advise you to continue supplicating Allah, The Exalted, and seek the help of your friends and relatives to look for a pious husband. It is permissible for a woman to look for a pious husband, as previously explained in Fatwa 82471.
Moreover, polygyny is permissible according to the Sharee‘ah; it is allowable for this man to take you as his second wife. However, it is required to avoid subjecting yourself to hardships and legal accountability.
Allah Knows best.
