All the messengers called for the worship of Allah alone and forbade the worship of idols such as trees, animals, the sun or the stars. All messengers are the most loyal people. They are Adam, Noah, Musa, Isa and others. We love and have faith in you all. Allah has given messengers many miracles to prove that what they say is true. Allah has given the Bible, in particular, to some of their messengers to provide answers and solutions to our problems. What is the role of a messenger? Thank Allah for sending us these great messengers!
