The faith is the most important science of religion at all, as it is the first duty of the taxpayer. When a person enters Islam, he must know monotheism before learning acts of worship. And when the Prophet, may God’s prayers and peace be upon him, sent Mu’adh to the people of Yemen, he said to him: Let the first thing you call them to do is to unite God Almighty, and if they know that, then tell them that God has imposed five prayers on them. The hadith indicated the importance of monotheism, which is the most important topic in the faith. The Messenger commanded the call to correct the belief before the call to actions. He gave priority to monotheism over the command to pray, and correcting the belief is very important. Because it is the foundation on which human actions are built, and the acceptance of good deeds depends on their safety from polytheism and disbelief.
