Obedience entails a concept of authority, and disobedience results in concept of displeasure of this authority and possible punishment. The concept of ultimate authority in the mind of all human beings always ends up with one. It is very difficult for humans to believe in an unseen one God. Therefore they invent visible shapes for Him like partners, sons, intercessors, idols, saints etc. In spite of these multiple Gods, idea of one Supreme Being overlooking all other gods always existed. This actually had to be because everyone experiences in this life the necessity for one decision maker in each house, family, village, city, or a country and thus concludes that there has to be one God who runs this world. That’s why we see monotheism or one Unseen God, being the central concept in human beings, but to accommodate their desire to be able to communicate with someone visible, they introduced the partners to God, in the shape of human beings, sons or idols or dead saints or holy people. So we see today atheist, idol worshippers, holding partners to God, ascribing sons to Him, saints and their graves worshippers, and those believers in only one unseen god.

There is no god worthy of worship except Allah and Muhammad is His messenger. I have faith in Allah and His Angels, His Books and His Messengers, and the Day of Judgement and that all good and evil and fate is from Almighty Allah and it is sure that there will be resurrection after death ** PROPHETS THIS IS A SAMPLE STUDY. God told all human beings that they will receive guidance from Him and they should follow it whenever it comes; the guidance was sent to all nations through prophets. (2-35) And We said: "O Adam! Dwell you and your wife in the Paradise and eat both of you freely with pleasure and delight of things therein as wherever you will, but come not near this tree or you both will be of the Zalimun (wrong-doers)". (2-36) Then the Shaitan (Satan) made them slip therefrom (the Paradise), and got them out from that in which they were. We said:"Get you down, all, with enmity between yourselves. On earth will be a dwelling place for you and an enjoyment for a time". (2-38) We said: "Get down all of you from this place (the Paradise), then whenever there comes to you Guidance from Me, and whoever follows My Guidance, there shall be no fear on them, nor shall they grieve. (2-39) But those who disbelieve and belie Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) such are the dwellers of the Fire, they shall abide therein forever.
