One of the primary reasons for Allāh sending Prophets was to establish His religion, promote harmony and unity, and eradicate divisions and differences.
Many individuals in addition to the Prophets have been mentioned in the Qur’ān by Allāh. Some have been mentioned explicitly, while others have been mentioned implicitly.
Islām is founded on fulfilling our obligations towards Allāh and towards His creations. Our obligation towards Allāh is to worship Him alone and not to attribute any partners to Him.
