Cephyr 13 gave you the reason why the time is reckoned differently by the KJV translators here.
----You stated----
Yet the four accounts of the crucifixion do not agree:
"And it was the third hour, and they crucified him." Mark 15.25
"...and about the sixth hour..." John 19:14
----End of excerpt----
It's important to understand the two ways they would indicate which hour of the day it was back then. And it is also important to understand how translators mess this up when they translate.
In Mark's account we're told that at the "third hour", they crucified him. Hebrews called 6am the 1st hour. And they called 9am the 3rd hour. However, they also would refer to 6am as the "hour six" of the day. In John's account, he says that Pilot handed him over to be crucified at about the "sixth hour". That is probably translated incorrectly. It should say, "hour six", which is 6am. If you go back and look at Jewish tradition, you should find that early in the morning, this ritual took place of setting a prisoner free. 6am is early in the morning, which lines up with what the gospels say.
So, John is saying that at 6am, he remembers Jesus being handed over by Pilot to be crucified. And then Mark says that three hours later, at the "third hour" (i.e. - 9am), Jesus is crucified.
If Muhommad had understand the Hebrew culture, Greek language, and the ways in which they identified what hour of the day it was, he would've picked up on this. The translators of the King James and many other translations simply don't realize they're translating "sixth hour" backward. It's a cultural thing. You need to understand the language and culture back then and the different ways they told time. If a person doesn't understand that, they will translate that incorrectly. Some translations have it correct:
John 19:14 - Weymouth New Translation
It was the day of Preparation for the Passover, about six o'clock in the morning. Then he said to the Jews, "There is your king!"
I would not trust a "non-Jew's" understanding of the Jewish culture and language useage from that time period. Better to trust the Jews on that, not a non-Jew such as Muhommad.
While the scriptures do say that Jesus' disciples abandoned Him on the night of His arrest nowhere does it indicate that they did not return to see the outcome. Given Jesus' foretelling of this event it would only make sense that they would return.
The records indicate that the women observed from afar off. Again there is no indication that none of these women did not walk to the cross later. Given that Jesus' death was imminent and they would be in a hurry to get his body entombed before the beginning of Passover it makes sense that they would approach the cross.
As far as these verses go.
Hsa 6:6 For I desired mercy, and not sacrifice; and the knowledge of God more than burnt offerings.
What God desires and what mankind give are two seperate things. God desires for all to be saved. However, God knows that not all people will be. If you read further in Hosea you see that what was desired was far different from what was given.
Mat 9:13 But go ye and learn what [that] meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.
This was Jesus telling the Pharisees what God wanted of them. Again what God wants and what man gives Him is not always the same. Since God's will is that all should come to repentance He can take a situation like the crucifixion and turn it into victory. Which is exactly what He did.
Besides you are wanting to try and discount 4 narratives that agree on the most important details. That Jesus was crucified and that he rose from the dead. Secular history records the crucifixion.
The earliest non-Christian reference to the crucifixion is likely from Mara Bar-Serapion, a Syriac writer who refers only to a "wise King" executed by the Jews.[36] Roman historian Tacitus, in his Annals (c. A.D. 116), mentions only in passing that "Christus...suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators..."[37] Similarly, Greek satirist Lucian refers to Jesus only as "the distinguished personage who introduced their novel rites, and was crucified on that account."[38]
Additionally, first-century Jewish historian Josephus (in a disputed passage[39]) records:
Now there was about this time Jesus, a wise man, if it be lawful to call him a man; for he was a doer of wonderful works, a teacher of such men as receive the truth with pleasure. He drew over to him both many of the Jews and many of the Gentiles. He was [the] Christ. And when Pilate, at the suggestion of the principal men amongst us, had condemned him to the cross, those that loved him at the first did not forsake him; for he appeared to them alive again the third day; as the divine prophets had foretold these and ten thousand other wonderful things concerning him. And the tribe of Christians, so named from him, are not extinct at this day.
—Josephus , Antiquities of the Jews - XVIII, 3:8-10
Though parts of this passage are believed to be interpolation by later editors what is left undoubtedly when those are removed is that a man named Jesus was crucified under Pilate.
Another possible Jewish reference to the crucifixion ("hanging" cf. Luk 23:39; Gal 3:13) is found in the Babylonian Talmud:
On the eve of the Passover Yeshu was hanged. For forty days before the execution took place, a herald went forth and cried, ‘He is going forth to be stoned because he has practised sorcery and enticed Israel to apostacy. Anyone who can say anything in his favour, let him come forward and plead on his behalf.’ But since nothing was brought forward in his favour he was hanged on the eve of the Passover!
—Soncino English Translation of the Babylonian Talmud, Sanhedrin 43a
Your assertion that none of the Gospels could be accurate because none of the writers were their is amazing considering you want to take the word of a man who was born 6 hundred years after the fact. Not a single person ever witnessed his so called revelation so to insist the correction came from God relies soley on the witness of the same man.
On Jesus' last words this is recorded.
"Father, forgive them, for they know not what they do."[Luke 23:34]
"Truly, I say to you, today you will be with me in Paradise."[Luke 23:43]
"Woman, behold, your son!" [John 19:25-27]
"E?li, E?li, la?ma sa?bach?tha?ni?" [Matthew 27:46] [Mark 15:34] (Aramaic for "My God, My God, why have you forsaken me?")
"I thirst."[John 19:28]
"It is finished."[John 19:30]
"Father, into your hands I commit my spirit!"[Luke 23:46]
All short utterances easily fit within a three hour period. The gospel writers simply wrote the parts that they remembered or the parts others present at the crucifixion remembered. ALL of them still agree on who was on the cross and the fact that He rose from the dead.
More secular evidence for the Gospel accounts are found when one turns to the darkness described. Thallus, Tertullian, and Phlegon all give accounts of the darkness. Phlegon even records the year it happened. The 202nd Olymiad (33AD).
But more to the point the verse in the koran suggests that people were conjecturing on who was crucified. NOONE had any doubts. Not the Jewish leaders, not the 1st century Christians, and not any true Christian today. However, many opinions have been given by muslims as to who was on the cross and what transpired.
1.Judas had Jesus' face put on him.
2.Some random person was made to look like Jesus.
3.Your own theory of substitution by one of the disciples.
The list still continues. It would seem that the conjecture lies with the muslim community my friend.
God bless
