how do you prove that without circular reasoning?
We are right because we follow Abu Baker and Umar as opposed to the Shiites who reject them.
How do you know they are good? Because our hadiths say so, our history says, our scholars say so....
etc. etc...
I showed a Du'a attributed to Ali that shows alternative history view. How do you know which one is correct?
It's time to refer things back to Quran primarily, and use Sunnah to unlock it's bright signs.
No more conjecture, forget your books for one second, forget the conjecture of Rijaal which you call ilmel rijaal for one second....
Is Quran showing something that cannot be proven? Or is showing a sacred history that is the only thing that could have possibly happened given what we know about God and his signs, and what we know about how the world is all over the place?
Is it showing history from the viewpoint of things that are possible to happen but possible to not happen, or it showing given what we know of the world today, this is surely what must have happened.
When God tells us of the sacred history of his Messengers, he is emphasizing on essential truths, revealing the structure of the world from it's evil side as well as it's bright side.
He reveals his plan and why his plan has not occurred and been fulfilled, but that he plans and plans again and again, always in benefit of humanity.
Hardly anyone moves an ounce to help him because they become fatalists. They turn away from the proof offered in Quran because it goes against their caprice and requires humility in form of sincere grief and repentance.
And the Navigators to the just city, the doors to ascension, the leaders who guide by his command, and the Captains are vitally important.
Their number in each covenant after the founder is also important. All this has been clearly emphasized and explained, and with the sacred history, the truth has been proven and admonishment has occurred to the believers.
