Desires...

Desires, fancies and fanaticisms play with them and devils occupy them so that they become excessive in their deviation. Allah says in this concern: Those who disbelieved from among the followers of the Book and the polytheists could not have separated (from the faithful) until there had come to them the clear evidence; a messenger from Allah, reciting pure pages, wherein are all the right ordinances.

And those who were given the Book did not become divided except after clear evidence had come to them . Quran 98:1-4 It is also not sufficient that a Jew or a Christian says, ‘I believe in Muhammad, but I will remain on my religion’, as I myself have heard from some Arab Christians. We say to such people that Allah does not accept from them except when they actually follow him.

Allah says in this concern: Those who follow the Messenger-Prophet, who can neither read nor write, whom they find written down with them in the Torah and the Gospel (who) enjoins them good and forbids them evil, and makes lawful to them the good things and makes unlawful to them impure things, and removes from them their burden and the shackles which were upon them; so (as for) those who believe in him and honor him and help him, and follow the light which has been sent down with him, these it is that are the successful .

Quran 7:157 This invitation from Allah the Almighty was not limited to the Jews and the Christians, all of whom represented “the People of the Book”, but it included all human beings with no exception. Allah the Almighty says: Say: O people!

surely I am the Messenger of Allah (S) to you all, of Him Whose is the kingdom of the heavens and the earth, there is no god but He; He brings to life and causes to die; therefore believe in Allah and His messenger, the Prophet, who can neither read nor write, who believes in Allah and His words, and you follow him so that you may walk in the right way . Quran 7:158 The Holy Qur'an is too clear in stating the obligation of following the Prophet (S) and not just believing in his prophethood.

This is the wisdom of Allah in sending the messengers.
