Muhammad repeatedly claims there’s clear proof. Let’s check:
Moses had Clear Proof
And Moses had certainly brought you clear proofs.
Then you took the calf [in worship] after that, while you were wrongdoers.
Koran 2:92
And We gave them clear proofs of the matter [of religion].
And they did not differ except after knowledge had come to them – out of jealous animosity between themselves.
Indeed, your Lord will judge between them on the Day of Resurrection concerning that over which they used to differ.
Koran 45:17
Jesus had Clear Proof
And We did certainly give Moses the Scripture [i.e., the Torah] and followed up after him with messengers.
And We gave Jesus, the son of Mary, clear proofs and supported him with the Pure Spirit.
But is it [not] that every time a messenger came to you, [O Children of Israel], with what your souls did not desire, you were arrogant?
And a party [of messengers] you denied and another party you killed.
Koran 2:87
Those messengers – some of them We caused to exceed others.
Among them were those to whom Allāh spoke, and He raised some of them in degree.
And We gave Jesus, the son of Mary, clear proofs, and We supported him with the Pure Spirit [i.e., Gabriel].
If Allāh had willed, those [generations] succeeding them would not have fought each other after the clear proofs had come to them.
But they differed, and some of them believed and some of them disbelieved.
And if Allāh had willed, they would not have fought each other, but Allāh does what He intends.
Koran 2:253
[The Day] when Allāh will say, “O Jesus, Son of Mary, remember My favor upon you and upon your mother when I supported you with the Pure Spirit [i.e., the angel Gabriel] and you spoke to the people in the cradle and in maturity; and [remember] when I taught you writing and wisdom and the Torah and the Gospel; and when you designed from clay [what was] like the form of a bird with My permission, then you breathed into it, and it became a bird with My permission; and you healed the blind [from birth] and the leper with My permission; and when you brought forth the dead with My permission; and when I restrained the Children of Israel from [killing] you when you came to them with clear proofs and those who disbelieved among them said, “This is not but obvious magic.”
Koran 5:110
And when Jesus brought clear proofs, he said, “I have come to you with wisdom [i.e., prophethood] and to make clear to you some of that over which you differ, so fear Allāh and obey me.
Koran 43:63
Jews and Christians have Clear Proof
Indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Scripture – those are cursed by Allāh and cursed by those who curse,
Koran 2:159
Mankind was [of] one religion [before their deviation]; then Allāh sent the prophets as bringers of good tidings and warners and sent down with them the Scripture in truth to judge between the people concerning that in which they differed.
And none differed over it [i.e., the Scripture] except those who were given it – after the clear proofs came to them – out of jealous animosity among themselves.
And Allāh guided those who believed to the truth concerning that over which they had differed, by His permission.
And Allāh guides whom He wills to a straight path.
Koran 2:213
And do not be like the ones who became divided and differed after the clear proofs had come to them.
And those will have a great punishment
Koran 3:105
Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land – it is as if he had slain mankind entirely.
And whoever saves one – it is as if he had saved mankind entirely.
And Our messengers had certainly come to them with clear proofs.
Then indeed many of them, [even] after that, throughout the land, were transgressors.
Koran 5:32
Their Messengers had Clear Proof
3:183 [They are] those who said, “Indeed, Allāh has taken our promise not to believe any messenger until he brings us an offering which fire [from heaven] will consume.”
Say, “There have already come to you messengers before me with clear proofs and [even] that of which you speak. So why did you kill them, if you should be truthful?”
184 Then if they deny you, [O Muḥammad] – so were messengers denied before you, who brought clear proofs and written ordinances and the enlightening Scripture.
Koran 3:183-184
Those cities – We relate to you, [O Muḥammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before.
Thus does Allāh seal over the hearts of the disbelievers.
Koran 7:101
Has there not reached them the news of those before them – the people of Noah and [the tribes of] ʿAad and Thamūd and the people of Abraham and the companions [i.e., dwellers] of Madyan and the towns overturned?
Their messengers came to them with clear proofs.
And Allāh would never have wronged them, but they were wronging themselves.
Koran 9:70
And We had already destroyed generations before you when they wronged, and their messengers had come to them with clear proofs, but they were not to believe. Thus do We recompense the criminal people.
Koran 10:13
Then We sent after him messengers to their peoples, and they came to them with clear proofs.
But they were not to believe in that which they had denied before.
Thus We seal over the hearts of the transgressors.
Koran 10:74
Has there not reached you the news of those before you – the people of Noah and ʿAad and Thamūd and those after them?
No one knows them [i.e., their number] but Allāh.
Their messengers brought them clear proofs, but they returned their hands to their mouths and said, “Indeed, we disbelieve in that with which you have been sent, and indeed we are, about that to which you invite us, in disquieting doubt.”
Koran 14:9
[We sent them] with clear proofs and written ordinances.
And We revealed to you the message [i.e., the Qur’ān] that you may make clear to the people what was sent down to them and that they might give thought.
Koran 16:44
And if they deny you – then already have those before them denied.
Their messengers came to them with clear proofs and written ordinances and with the enlightening Scripture.
Koran 35:25
That was because their messengers were coming to them with clear proofs, but they disbelieved, so Allāh seized them.
Indeed, He is Powerful and severe in punishment.
Koran 40:22
And a believing man from the family of Pharaoh who concealed his faith said, “Do you kill a man [merely] because he says, ‘My Lord is Allāh’ while he has brought you clear proofs from your Lord? And if he should be lying, then upon him is [the consequence of] his lie; but if he should be truthful, there will strike you some of what he promises you. Indeed, Allāh does not guide one who is a transgressor and a liar.
Koran 40:28
And Joseph had already come to you before with clear proofs, but you remained in doubt of that which he brought to you, until when he died, you said, ‘Never will Allāh send a messenger after him.’
Thus does Allāh leave astray he who is a transgressor and skeptic.”
Koran 40:34
And when their messengers came to them with clear proofs, they [merely] rejoiced in what they had of knowledge, but they were enveloped by what they used to ridicule.
Koran 40:83
Our Verses are Clear Proof
And We have certainly revealed to you verses [which are] clear proofs, and no one would deny them except the defiantly disobedient.
Koran 2:99
But if you slip [i.e., deviate] after clear proofs have come to you, then know that Allāh is Exalted in Might and Wise.
Koran 2:109
The month of Ramaḍān [is that] in which was revealed the Qur’ān, a guidance for the people and clear proofs of guidance and criterion.
So whoever sights [the crescent of] the month, let him fast it; and whoever is ill or on a journey – then an equal number of other days.
Allāh intends for you ease and does not intend for you hardship and [wants] for you to complete the period and to glorify Allāh for that [to] which He has guided you; and perhaps you will be grateful.
Koran 2:185
They said, “Never will we prefer you over what has come to us of clear proofs and [over] He who created us. So decree whatever you are to decree. You can only decree for this worldly life.
Koran 20:72
Say, [O Muḥammad], “Indeed, I have been forbidden to worship those you call upon besides Allāh once the clear proofs have come to me from my Lord, and I have been commanded to submit to the Lord of the worlds.”
Koran 40:66
False Prophecy
They will say, “Did there not come to you your messengers with clear proofs?”
They will say, “Yes.”
They will reply, “Then supplicate [yourselves], but the supplication of the disbelievers is not except in error [i.e., futility].”
Koran 40:50
Conclusion
Muhammad claimed others had “clear proof” but was unable to prove the clear proof to his tribe.
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
But, Infidel, the Psalms? In Muhammad’s Koran, Muhammad claims that the mountains and birds exalt Allah with the Psalms:
And We subjected the mountains to exalt [Us], along with David and [also] the birds.
Excerpt, Koran 21:79
And We certainly gave David from Us bounty.
[We said], “O mountains, repeat [Our] praises with him, and the birds [as well].”
Excerpt, Koran 34:10
Indeed, We subjected the mountains [to praise] with him, exalting [Allah] in the [late] afternoon and [after] sunrise.
Koran 38:18
Obviously, the birds do not praise Allah.
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
