First: People’s need for advocacy:

Calling for a legal necessity for all people, regardless of their races, colours, tongues, and culture, to explain the truth, spread fear, bring benefits, ward off evil, regulate a person’s relationship with his Lord, and his relationship with creatures, so that he knows his money and what he owes.

All of creation is in dire need of the call to God’s religion with insight due to their inability to reach out to goodness, righteousness, guidance, and success on their own. Man is limited in thinking in this universe, limited in his resolve, unable to know what will improve his affairs in the two worlds. His need for religion is one of the necessities of his life, and one of the complements of his existence and creation, and his need for religion. Such as his need for air and water. This is why God Almighty sent the Messengers, peace and blessings be upon them, and sent down the heavenly books to uplift this human being, fill his shortcomings, and bring him out of darkness into light.

Second: The ruling on calling people to God:

The scholars agreed on the necessity of the Islamic call to Islam, and that agreement was a consensus that was concluded in the era of the Companions, and then the era of the Successors - may God be pleased with them - and the consensus will not be broken if Muslims today neglect it and sit back and do not fulfill its rights, and the scholars differed regarding it: - Is it an individual obligation, or a sufficiency obligation?
