What is the ruling on selling statues from home and delivering them to customers? Is it permissible to make them? And is an unmarried woman's money unblessed?

The questioner, sister, did well by leaving university for the reason mentioned. There is no harm in a woman selling what she makes in her home, and her earnings are not deprived of blessings because she is a woman. Lawful earnings, whether from a man or a woman, are good and blessed, for the Prophet, peace and blessings be upon him, said: "A man's work with his hand, and every righteous sale." A righteous sale is one that is free from legal prohibitions. The default rule is the permissibility of earning and trading for both men and women, provided that legal controls are adhered to, such as modesty, not revealing adornment, and avoiding unlawful mixing. The wives of the Companions – such as Umm Al-Mu'minin Zaynab bint Jahsh and the wife of Abdullah ibn Mas'ud – used to work, earn, and give charity. As for making and selling cartoon character figurines, that has a different ruling.
