Centuries old geopolitics my friend right from the time when Hazrat Umer (faced with an awkward situation) spared the life of persian military leader Harmazan.
True but nonetheless, it is current geopolitics that the thread is based on.
Regarding your point that Quran is incomplete without any hearsay .......... my friend this is wrong on so many levels that I don't dare think of this. Quran is simple and complete to understand I didn't once have any problems understanding while reading a bare translation. But shedding my preconceived ideas helped me a lot to understand the clear message. There is only one Hadeeth and that is Quran.
If Holy Quran was simple, then there would be no confusion today. Holy Quran was revealed in classical language of Arabic which to this day modern Arabs don't grasp to the similar understanding of each verses in the classical Arab language. On the top of it, if they take Holy Quran alone, that leaves out the commentary which includes the context and background, and without them, the verse can be literally manipulated.
For example, kill the unbeliever. See how easy it is to manipulate the verse? If you include the context and background, then you will realize that they discuss the whole scenario which had unpleasant exchange between Quraish and Muslims in regards to negotiation in the past which resulted into the wars which Muslims partook only to defend themselves against the attack.
Take out the whole context and background meaning Authentic Hadiths, you are gonna get Wahabi and Salafi in angry mood shouting 'unbeliever'. Now you see why there is the confusion to begin with.
Even then, we are relying on the translation which is often lost in translation. Without context and the background, the word 'Aramaic' is changed to Father in English very fast. That is what happened in Bible leaving out the context and the background. Jesus (PBUH) invoked the name of GOD in Aramaic 'ELLAH' which is similar to ALLAH in Arabic and it means ONE GOD ONLY, BEGETS NOT NOR BEGOTTEN AND THERE IS NONE LIKE UNTO ALLAH. In fact, Surah Ikhlas summed it simple and precisely to the definition of ALLAH aka ELLAH; A CREATOR.
Now imagine Bible in English without the context and the background and it says Father which implies Jesus (PBUH) as son of GOD which changes the whole game overall if we are to take verses of Bible into literal.
For starters you quoted how would we know about 5 times prayers? Spare sometime and see how many times and at what times Zoroastrians pray.
That doesn't change the lifestyle and ritual of Islam as we know today is derived from Authentic hadiths. Besides, Islam is not inspired by Zoroastrians. It is inspired by the Surah Al Isra which the recording of Prophet Muhammad (PBUH)'s journey to heaven recorded in the Authentic hadiths which details the meeting with Prophet Moses (PBUH). And it was Prophet Moses (PBUH) that convinced Prophet Muhammad (PBUH) to shorten the prayers from 50 to 5 times a day which then is approved by the Merciful GOD.
Even then, Merciful GOD promised to rewards 50 prayers for five times a day meaning if we pray five times a day, we will be rewarded 50 times of prayer a day. Beauty, right?
Read this thread and if you feel comfortable we can continue our discussion there. If you don't mind I am occupied right now but if you tag me in this other thread we can continue there

Of course, i can understand. If you don't mind my advise, you are playing dangerously close to the edge by discounting the whole exercise of Islam backed by Authentic even though you are barely knowledgeable to begin with.
If you pray five times a day, that is because of Authentic hadiths which you call hearsay. Then there is Ramadan coming up which Muslims will be planning to fast for the whole month is thanks to Authentic Hadiths.
You are not going to find the information on procedure of prayers, ablution, Ramadan, rituals of Hajj and Umhra and many more on elsewhere, and certainly not on Holy Quran unless we analyze the numerical signs and orders by each Surahs. One member did that in the past. I haven't understood so i am not gonna go in detail.
