The Qur'an was sent down to humanity as a guide to the right path and for obtaining God's mercy. It gives important knowledge about what Prophet Muhammad (may God bless him and grant him peace) did, his message to unbelievers, and his struggle to spread God's religion. It also gives important information about the lives of Prophet Moses, Prophet Joseph, Prophet Jesus, Prophet Jonah, Prophet Lot , Prophet Noah, Prophet Shu'aib, and Prophet Salih (peace be upon them all). Like our Prophet (may God bless him and grant him peace), they invited people to faith in God, warned them about the afterlife, and relayed true religion so that their people would adopt high moral standards.
