How can one respond to the question: "If God exists and controls everything, then why do people kill each other?" and to the misconception that "there is injustice towards women in the religion of Islam"?

The proofs of God's existence are numerous, including scriptural and cosmic evidence. Denying His existence due to the presence of killing is incorrect; rather, the existence of both good and evil is a proof of God's existence through His management of wills for a divine wisdom. God is the Creator of all things, and He created evil for a wisdom. If He willed, He could prevent its occurrence through an act, as He states: "And if Allah had willed, those [generations] after them would not have fought each other after the clear proofs had come to them. But they differed, and some of them believed and some disbelieved. And if Allah had willed, they would not have fought each other, but Allah does what He intends." (2:253) Accusing Islam of oppressing women is a fabrication; rather, Islam honored and treated them justly. Debating with people of falsehood has its foundations and regulations, and it is more appropriate for men to call men and women to call women. It is not permissible to converse with a non-mahram woman except out of necessity and while observing the Sharia regulations.
