What or who is “Pure” in the Koran?
Jesus is Pure

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 [i.e., the angel Gabriel].
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
He said, “I am only the messenger of your Lord to give you [news of] a pure boy [i.e., son].”
Koran 19:19
[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
Lot’s Visitors are Pure

But the answer of his people was only that they said, “Evict them from your city! Indeed, they are men who keep themselves pure.”
Koran 7:82
Then Muhammad gets confused in a later repetition:
But the answer of his people was not except that they said, “Expel the family of Lot from your city. Indeed, they are people who keep themselves pure.”
Koran 27:56
Pure Nonsense

Whatever is in the heavens and whatever is on the earth is exalting Allāh, the Sovereign, the Pure, the Exalted in Might, the Wise.
Koran 62:1
The idol Allah doesn’t know that our Earth is in the “heavens” and is a sphere. Allah is “pure” nonsense.
He is Allāh, other than whom there is no deity, the Sovereign, the Pure, the Perfection, the Grantor of Security, the Overseer, the Exalted in Might, the Compeller, the Superior.
Exalted is Allāh above whatever they associate with Him.
Koran 59:23
In space, there’s no “above”. Allah is “pure” nonsense.
Abrogation is Pure

16:101 And when We substitute a verse in place of a verse – and Allah is most knowing of what He sends down – they say, “You, [O Muhammad], are but an inventor [of lies].”
But most of them do not know.
102 Say, [O Muhammad], “The Pure Spirit has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims.”
Koran 16:101-102
Murder isn’t Pure

So they set out, until when they met a boy, he [i.e., al-Khiḍr] killed him.
[Moses] said, “Have you killed a pure soul for other than [having killed] a soul? You have certainly done a deplorable thing.”
Koran 18:74
Rain is Pure

And it is He who sends the winds as good tidings before His mercy [i.e., rainfall], and We send down from the sky pure water
Koran 25:48
Pure, Pasteurized Milk

And indeed, for you in grazing livestock is a lesson.
We give you drink from what is in their bellies – between excretion and blood – pure milk, palatable to drinkers.
Koran 16:66

Pure Bottles of Wine

They will be given to drink [pure] wine [which was] sealed.
Koran 83:25
No one is Pure

The ones whom the angels take in death, [being] good and pure; [the angels] will say, “Peace be upon you. Enter Paradise for what you used to do.”
Koran 16:32
Angels don’t take anyone in death, let alone speak to them.
Have you not seen those who claim themselves to be pure?
Rather, Allāh purifies whom He wills, and injustice is not done to them, [even] as much as a thread [inside a date seed].
Koran 4:49
O you who have believed, do not follow the footsteps of Satan.
And whoever follows the footsteps of Satan – indeed, he enjoins immorality and wrongdoing.
And if not for the favor of Allāh upon you and His mercy, not one of you would have been pure, ever, but Allāh purifies whom He wills, and Allāh is Hearing and Knowing.
Koran 24:21
But those who feared their Lord will be driven to Paradise in groups until, when they reach it while its gates have been opened and its keepers say, “Peace be upon you; you have become pure; so enter it to abide eternally therein,” [they will enter].
Koran 39:73
Nothing happened for 1400 years. Muhammad was impure and a liar.
Those who avoid the major sins and immoralities, only [committing] slight ones.
Indeed, your Lord is vast in forgiveness.
He was most knowing of you when He produced you from the earth and when you were fetuses in the wombs of your mothers.
So do not claim yourselves to be pure; He is most knowing of who fears Him.
Koran 53:32
We aren’t produced from the earth. Also, note that it’s OK to commit “slight” sins and immoralities” in Islam.
Unquestionably, for Allāh is the pure religion.
And those who take protectors besides Him [say], “We only worship them that they may bring us nearer to Allāh in position.”
Indeed, Allāh will judge between them concerning that over which they differ.
Indeed, Allāh does not guide he who is a liar and [confirmed] disbeliever.
Koran 39:3
Conclusion
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
