What are the inviolable things of Allah? And what does "violating the inviolable things of Allah" mean?

The word "mahārim" is the plural of "muharram," and it refers to the prohibitions that Allah, the Almighty, has forbidden, such as polytheism (shirk), adultery (zina), drinking alcohol, consuming usury (riba), killing a soul, and disobeying parents. The meaning of "violating the sacred limits (mahārim) of Allah" is to commit these prohibitions and sins. So, whoever commits a forbidden act has violated the sacred limits of Allah.
