What is the ruling of Islamic law concerning zina (unlawful sexual intercourse) committed under duress and by rape, and what is the expiation for someone upon whom this befell while she was a child?

Adultery is an abomination and a major sin, with its punishment being one hundred lashes for the unmarried and stoning for the married. Its punishment becomes even more heinous if committed between Mahrams. Whoever falls into this abomination must offer sincere repentance and conceal their sin, observe the obligatory prayers and increase in voluntary acts of worship, occupy themselves with obedience to Allah, avoid masturbation and satanic delusions, endure patiently against sin, reduce food intake, fast, and associate with righteous women.
