ما حكم تسمية المولود باسم "ليون"؟

There is no objection to naming someone "Lion" (ليون) if it carries the meaning mentioned, as long as it does not imply servitude to other than Allah, contradict religion and morals, or pertain to a name exclusive to disbelievers or one of their leaders hostile to Islam. It is preferable to choose good Arabic names, because a name is a person's facade.
