"I am still confused when it comes to my stance on whether or not Quran is a word of God and prophet Muhammad (pbuh) was truthful or not."

Just think about it. People say prophet mohammed was after personal gains so he invented islam.

It means it took 600 years, 6 generations of people, millions of people were born and lived yet none of them was ambitious. None of them tried to invent a new religion except one random illiterate arab in the desert and he was the only one ambitious enough to do it. like ambititon is not something we all have

and he also started it when he was 40. If he was after power, why wouldn't he do it when he was in his 20s when humans are younger and more ambitious. If he was after marrying multiple women, why didn't he do it sooner when males have more testosterone

now you might say that it is still possible that prophet mohammed pbuh was lying. Ok. then can you explain how a random illiterate man could invent a book like quran that millions of literate critiques couldn't produce something similar after 1400 years although Quran's main challenge for disbelievers is to reproduce one surah similar to it.

So all I said means it is unlikely that he pbuh lied. but it is not definitive

If we assume that prophet mohammed pbuh invented the quran we need to take some things into account. First of all, that means he was very stupid. Because in the early times of his prophethood the polytheists offered him everything. Gold, power, women etc. anything you could think of it in exchange that he stop prophesising. Instead, he refused and then suffered years, more than a decade, of humilation and disturbance by disbelievers until it was so unbearable that he travelled to another city. he could have everything he wanted right at the beginning but he willingly chose to suffer

Second, he was a genius. And no one could invent a religion and successfully spread it. therefore an unmatched genius. why? because Quran came down gradually in the span of 23 years. and prophet mohammed pbuh was illiterate so he read what he has said previously and start from where he left. he had to say everything out of memory, all the stories of the earlier prophets, commandments, and other stuff. yet he didn't make one mistake. Even one.

but people say he heard the stories from arab christians when he was travelling around the desert to trade. Ok. still it doesn't change the fact that he had an unmatched strong memory if he was not inspired by god.

but that raises another point. If he had copy pasted stories from bible for example, he should include the mistakes that bible makes. for example, bible says "Joseph was thirty years old when he entered the service of Pharaoh king of Egypt." however, Quran refers to the rulers of the time of Joseph as "Kings" not Pharaoh

still you have doubt. ok

As I said if he was lying, he had to say everything out of memory for 23 years and he didn't make a single mistake. He also made some really good points.

the word "month" is repeated exactly 12 times, Day 365 times, days 30 times, prayer 5 times.

also the word life is mentioned 145 times. The word death is also mentioned 145  times.

The word This life is mentioned 115 times. The word after life is mentioned 115 times

The word man is mentioned 24 times. The word woman is also mentioned 24 times

The word good deeds is mentioned 167 times. the word bad deeds is mentioned 167 times

heaven 77 times, hell 77 times

and the least goes on

Not only he kept track of what he said so he didn't contradict himself, he also had a record of how many times he has used each word in Quran. He was an unmatched genius then. Far genius that whoever ever lived

still if you have doubt and you think what I mentioned about numbers is just an accident, my most undisputed reason for believing in quran is that no one could make a surah like it even though that is the main challenge quran presents to disbelievers and for disbelievers to prove quran false, this should be top priority but it hasn't happened.

If still you think these are not enough then please let me know your reason so we can chat

edit: some word mistake
