What is the difference between Ijz (helplessness) and Freewill. Are they linked in any way?

Ijz (helplessness) and free-will are two different subjects. Ijz is required in relation to God. When you discover the position of the Creator, you also discover the position of man in relation to Him. It is this discovery that is called ijz. When one develops the quality of ijz, it finds expression in relation to other humans as modesty. The word "ijz" is used in relation to God and, the word "tawazu" (modesty) is used in relation to human beings.

Free-will is a quite different quality. It means freedom to make decisions. God Almighty has given us this quality not as a gift, but as a test
