What is the reason for the increase in the number of spinsters, and is it fate and divine decree, or are there other reasons for it?

Spinsterhood may have ordinary or extraordinary causes, such as magic, and it is not permissible to accuse anyone without proof. This phenomenon can be eliminated by searching for the causes and solutions, while seeking Allah Almighty's help and supplicating to Him, for He answers the prayer of the distressed and removes harm, and "If Allah touches you with harm, there is no remover of it except Him; and if He intends for you good, then there is no repeller of His bounty. He causes it to reach whom He wills of His servants. And He is the Forgiving, the Merciful."
