." Sura Mai'da (5:72) "And to (the tribe of) 'Aad (We sent) their brother Hud (the prophet). He said: O my people! serve Allah, you have no god other than Him ... ." Sura A'raf (7:65) "Certainly We sent Noah to his people, so he said: O my people! serve Allah, you have no god other than Him." Sura A'raf (7:59) "And to (the tribe of) Thamood (We sent) their Salih (the prophet). He said: O my people!

serve brother you have no god other than Him; clear proof indeed Allah, has come to you from your Lord ... ." Sura A'raf (7:73) "And to Midi an (We sent) their brother Shu'aib (the prophet). He said: O my people!

serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord; so give full measure and weight, and do not diminish to people their things, and do not make mischief in the land after its reform; this is better for you, if you are believers." Sura A'raf (7:85) "And (We sent) Abraham when he said to his people: Serve Allah, and be careful of (your duty to) Him; this is best for you, if you did but know." Sura Ankabut (29:16) "And certainly We raised in every nation an apostle, (proclaiming): Serve Allah and shun false gods.

So there were some of them (nations) whom Allah guided, and there were others upon whom error had just hold." Sura Nahl (16:36) "And We did not send before you any apostle but We revealed to him, that there is no god but Me (Allah), therefore serve Me." Sura Anbiya (21:25) All the messages have a single aim and advocate good conduct and behaviour, and call people to be righteous, to purify their souls, organize life on the basis of truth and justice, and to fight against injustice , transgression and corruption.

The Prophets themselves embodied the highest ideals and the noblest manners and were worthy models of emulation as Allah the Exalted says: "And we made them Imams (leaders) who guided (people) by Our command, and We revealed to them the doing of good and the keeping up of prayer and the giving of the alms, and Us (alone) did they serve." Sura Anbiya (21:73) While discussing the elements common in all the divine invitations and messages, we should not forget to refer to an ambiguity which has been talked about a lot within the circles of the Orientalists and their followers whose skepticism is the result of their hostile attitude towards Islam.
