The call of all prophets and messengers agreed on universal fundamentals. The fundamentals of all the messengers’ calls are the same. Almighty Allah says: {He (Allâh) has ordained for you the same religion (Islâmic Monotheism) which He ordained for Nûh (Noah), and that which We have revealed to you (O Muhammad [sal-Allâhu ‘alayhi wa sallam]), and that which We ordained for Ibrâhîm (Abraham), Mûsâ (Moses) and "Iesa (Jesus) saying you should establish religion (i.e. to do what it orders you to do practically), and make no divisions in it (religion) (i.e. various sects in religion).}(Ash-Shu’arâ’:13)
It is for this reason that the religion all the prophets called to is the same. Allah says: {51. O (you) Messengers! Eat of the Taiyibât [all kinds of Halâl (legal) foods which Allâh has made legal (meat of slaughtered eatable animals, milk products, fats, vegetables, fruits, etc.], and do righteous deeds. Verily! I am Well-Acquainted with what you do. 52. And verily! This your religion (of Islâmic Monotheism) is one religion, and I am your Lord, so keep your duty to Me.}(Al-Mu’minûn:51-52)
This is the case, although the laws of each prophet differ, Allah says: {To each among you, We have prescribed a law and a clear way.}(Al-Mâ’idah:48)
If these laws contradict these fundamentals, it (the religion) would no longer be wise, good for people’s interests or compassionate with them. It is, therefore, impossible that the laws of the true religion come contrary to its fundamentals. Allah says: {And if the truth had been in accordance with their desires, verily, the heavens and the earth, and whosoever is therein would have been corrupted!}(Al-Mu’minûn:71)
To believe in Allah, His angels, His books, His messengers and in the Last Day, as well as destiny, whether good or bad, are among the issues agreed upon between the messengers and are stated in the messages. Allah Almighty says: {The Messenger (Muhammad SAW) believes in what has been sent down to him from his Lord, and (so do) the believers. Each one believes in Allâh, His Angels, His Books, and His Messengers. They say, “We make no distinction between one another of His Messengers” - and they say, “We hear, and we obey. (We seek) Your Forgiveness, our Lord, and to You is the return (of all) }(Al-Baqarah:285)
The messengers and their messages command people to worship Allah Alone, without a partner, and to deem Him too exalted to have a wife, a son, a partner, a peer or an equal, and also denounce the worship of idols. Allah says: {And We did not send any Messenger before you (O Muhammad [sal-Allâhu ‘alayhi wa sallam]) but We inspired him (saying): Lâ ilâha illa Ana [none has the right to be worshipped but I (Allâh)], so worship Me (Alone and none else).}(Al-Anbiyâ’:25)
Furthermore, they command people to follow Allah’s path and not any other inconsistent paths, to fulfill covenants, give full measure and weight in justice, honor one’s parents, be just with the people, and be honest in speech and action, and they prohibit immorality, both obvious and hidden, as well as sin and oppression without right, the killing of children and also the killing of oneself without right, usury, consuming the wealth of orphans, waste, arrogance and consuming people’s wealth unlawfully.
Belief in the Last Day:
Every man knows for sure that he will inevitably die one day, but what is his fate after death? Will he be wretched or blessed? All prophets and messengers conveyed and stated to their people that they will be resurrected and held accountable for their actions. If they were good, then they will be rewarded, and if they were evil, then they will be punished. This matter – that of the resurrection and accountability – is recognized by sound minds, and supported by divine laws. The All-Capable, All-Knowing and All-Wise Creator is too exalted to create His creation in vain and to leave them in vain. He (Glorified be He) says: And We created not the heaven and the earth and all that is between them without purpose! That is the consideration of those who disbelieve! Then woe to those who disbelieve (in Islâmic Monotheism) from the Fire!(Sâd:27)
Rather, He originated His creation for a great wisdom and purpose. Allah says: {And I (Allâh) created not the jinns and humans except they should worship Me (Alone){.(Az-Zâriyât:56)
Therefore, it is not befitting for this All-Wise Lord to consider those who obey Him and those who do not as being equal. Allah says: {Shall We treat those who believe (in the Oneness of Allâh Islâmic Monotheism) and do righteous good deeds, as Mufsidûn (those who associate partners in worship with Allâh and commit crimes) on earth? Or shall We treat the Muttaqûn (pious - see V.2:2), as the Fujjâr (criminals, disbelievers, wicked, etc)?}(Sâd:28)
It is for this reason and due to His Perfection and Wisdom and the Greatness of His ability, that he will resurrect His creatures on the Day of Resurrection to account every man for his work; rewarding those who have done good deeds and punishing those who have committed evil actions. The Almighty says: {that He may reward with justice those who believed (in the Oneness of Allâh - Islâmic Monotheism) and did deeds of righteousness. But those who disbelieved will have a drink of boiling fluids and painful torment because they used to disbelieve.} (Yûnus:4)
It is extremely easy for Allah to resurrect humans to hold them responsible after their death. Did not He, the Almighty, create the heavens and the earth?! If He (Glorified be He) originated the creation without a previous example, then would He not be able to re-create it?! Allah says: {Do they not see that Allâh, Who created the heavens and the earth, and was not wearied by their creation, is Able to give life to the dead? Yes, He surely is Able to do all things.}(Al-Ahqâf:33)
The Almighty Also says: {Is not He, Who created the heavens and the earth Able to create the like of them? Yes, indeed! He is the All-Knowing, Supreme Creator.}(Yâ-¬Sîn:81)
One who is capable of giving life in the first place is unquestionably able to repeat it.The Exalted says: {And He it is Who originates the creation, then will repeat it (after it has been perished), and this is easier for Him. His is the highest description (i.e. none has the right to be worshipped but He, and there is nothing comparable unto Him) in the heavens and in the earth. And He is the All-Mighty, the All¬-Wise.}(Ar¬-Rûm:27)
The dead were even resurrected in this life, in front of Prophet Abraham (pbuh), by the will of Allah. Allah says: {And (remember) when Ibrâhim (Abraham) said, “My Lord! Show me how You give life to the dead.” He (Allâh) said: “Do you not believe?” He [Ibrâhim (Abraham)] said: “Yes (I believe), but to be stronger in Faith.” He said: “Take four birds, then cause them to incline towards you (then slaughter them, cut them into pieces), and then put a portion of them on every hill, and call them, they will come to you in haste. And know that Allâh is All-Mighty, All-Wise.}(Al-Baqarah:260)
They were also resurrected by Allah’s permission by the hands of Christ (pbuh).The Almighty says: {(Remember) when Allâh will say (on the Day of Resurrection). “O ‘Iesa (Jesus), son of Maryam (Mary)! Remember My Favour to you and to your mother when I supported you with Rûh¬ul¬Qudus [Jibrael (Gabriel)] so that you spoke to the people in the cradle and in maturity; and when I taught you writing, Al¬Hikmah (the power of understanding), the Taurât (Torah) and the Injeel (Gospel); and when you made out of the clay, as it were, the figure of a bird, by My Permission, and you breathed into it, and it became a bird by My Permission, and you healed those born blind, and the lepers by My Permission, and when you brought forth the dead by My Permission; and when I restrained the Children of Israel from you (when they resolved to kill you) since you came unto them with clear proofs, and the disbelievers among them said: ‘This is nothing but evident magic. }(Al-Mâ’idah:110)
