The following is taken from the noble Quran, chapter 18 (the Cave). This surah talks about how the Alexander the great, a pagan warlord who believed in many gods, was also a Muslim - (maybe talking about Mohammad (SAW) where he once worshipped Allah's daughters).
The following analysis is taken from the following website: http://inthenameofallah.org/quran%20chapter%2018.html. I would normally add my own commentary, but the authors do a good job questioning Mohammad's (SAW) inspiration from Allah.
83 They ask thee concerning Zul-qarnain. Say "I will rehearse to you something of his story."
#2428 Literally, "the Two-horned one", the King with the Two Horns, or the Lord of the Two Epochs. Who was he? In what age, and where did he live? The Qur-an gives us no material on which we can base a positive answer. Nor is it necessary to find an answer, as the story is treated as a Parable. Popular opinion identifies Zul-qarnain with Alexander the Great. An alternative suggestion is an ancient Persian king, or a pre-historic Himyarite King. Zul-qarnain was a most powerful king, but it was Allah, Who, in His universal Plan, gave him power and provided him with the ways and means for his great work. His sway extended over East and West, and over people of diverse civilisations. He was just and righteous, not selfish or grasping. He protected the weak and punished the unlawful and the turbulent. Three of his expeditions are described in the text, each embodying a great ethical idea involved in the possession of kingship or power.#
*** The Quran shows an incredible propensity to jump from one subject to another, completely unconnected to the first, either in sequence or in time.
What has Alexander the Great got to do with the companions of the Cave? With Moses? ***
84 Verily We established his power on earth and We gave him the ways and the means to all ends.
85 One (such) way he followed
86 Until when he reached the setting of the sun He found it set in a spring of murky water: near it he found a People: We said: "O Zul-qarnain! (thou hast authority) either to punish them or to treat them with kindness."
*** In the verses 83- 106 we find several astounding revelations about Muhammad's Quran:
First, is that the Quran declares that the SUN sets in a spring of murky waters.
Second, that where the SUN sets, there are an unknown people.
Third, that Allah addressed Zul Qarnain and gave him authority on how to treat these people.
Fourth, Zul Qarnain, who is supposed to be Alexander the Great, who was a pure pagan, has now been made a Muslim.
Fifth, and most important of all, an almost identical set of verses are mentioned in the Jahiliyah period regarding a Tubba in the line of Himyar whose name was Sa'b Dhu'l-Qarnayn (Sa'b the Two Horned).
Moreover, the author of the following lines was Hassan b Thabit, who was Muhammad's secretary:
"Ours the realm of Dhu 'l-Qarnayn the glorious Realm like his was never won by mortal king.
Followed he the SUN to view its setting
When it sank into the somber ocean-spring;
Up he clomb to see it rise at morning,
From within its Mansions when the East it fired;
All day long the horizons led him onward,
All night through he watched the stars and never tired.
Then of iron and of liquid metal
He prepared a rampart not to be o'erpassed,
Gog and Magog there he threw in prison
Till on Judgement Day they shall awake at last"
The above Arabic text is found in Von Kremer's Altarabische Gedichie ueber die Volgssage von Yemen p.15 (No. viii,1.6 sqq). The reader can see from the above poem, that it contains all the ingredients that the Quran plagiarized from it, almost verbatim. Hence, when a Quranic verse dares the reader to show that any other BUT the Quran has such verses, one can easily show the above as proof. There are even more verses in the Quran that were plagiarized from the poems of Imru'l Qays and others ***87 He said: "Whoever doth wrong him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before).
88 "But whoever believes and works righteousness he shall have a goodly reward and easy will be his task as we order it by our command."
89 Then followed he (another) way.
90 Until when he came to the rising of the sun he found it rising on a people for whom We had provided no covering protection against the sun.
91 (He left them) as they were: We completely understood what was before him.
92 Then followed he (another) way
93 Until when he reached (a tract) between two mountains he found beneath them a people who scarcely understood a word.
18:94> They said: "O Zul-qarnain! the Gog and Magog (people) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them?"
#2439 What we are mainly concerned with is its interpretation. The Conqueror had now arrived among a people who were different in speech and race from him, but not quite primitive, for they were skilled in the working of metals, and could furnish blocks (or bricks) of iron, melt metals with bellows or blow-pipes, and prepare molten lead (xviii. 96). Apparently they were a peaceable and industrious race, much subject to incursions from wild tribes who are called Gog and Magog. Against these tribes they were willing to purchase immunity by paying the Conqueror tribute in return for protection. The permanent protection they wanted was the closing of a mountain gap through which the incursions were made.#
*** Yet once more, the Quran misunderstands the Biblical event and makes its own 'version' of the story.
What is more disturbing but understandable, is the fact that the interpreter has had to create his own scenario to explain the discrepancies away, hence compounding the deception upon the not so knowledgeable reader.
In the Bible, Gog are a people while Magog is a land. Ezekiel 38:2 " Son of man, set your face against Gog, the land of Magog, the chief prince of Meshech and Tubal, and prophesy against him," Also, Ezekiel's prophesies were in the 6th century BCE while Zul-Qarnain refers to Alexander the Great of the 4th who knew nothing about Gog or Magog ***
95 He said: "(The power) in which my Lord has established me is better (than tribute): help me therefore with strength (and labor): I will erect a strong barrier between you and them:
96 "Bring me blocks of iron." At length when he had filled up the space between the two steep mountain sides he said "Blow (with your bellows)." Then when he had made it (red) as fire he said: "Bring me that I may pour over it molten lead."
97 Thus were they made powerless to scale it or to dig through it.
98 He said: "This is a mercy from my Lord: but when the promise of my Lord comes to pass He will make it into dust; and the promise of My Lord is true."
99 On that day We shall leave them to surge like waves on one another; the trumpet will be blown and We shall collect them all together.
100 And We shall present Hell that day for Unbelievers to see all spread out
101 (Unbelievers) whose eyes had been under a veil from Remembrance of Me and who had been unable even to hear.
102 Do the Unbelievers think that they can take my servants as protectors besides Me? Verily We have prepared Hell for the Unbelievers for (their) entertainment.
103 Say: "Shall we tell you of those who lose most in respect of their deeds
104 "Those whose efforts have been wasted in this life while they thought that they were acquiring good by their works?"
105> They are those who deny the Signs of their Lord and the fact of their having to meet Him (in the Hereafter): vain will be their works nor shall We on the Day of Judgment give them any Weight.
106> That is their reward Hell; because they rejected Faith and took My Signs and My Messengers by way of jest.
