Intentional tampering? History isn’t black-and-white, dumbass, there's going to be conflicting sources and interpretations. You cling to two accounts like they’re the holy grail, but guess what? That’s not how historical analysis works. Ibn Jareer al-Tabari is a historical source that is respected in Islamic historiography, not "a goggle doc concocted in a basement of mine." Crack a book instead of cracking stupid jokes. You dismiss actual sources because they don’t fit your narrative. That’s called intellectual laziness, bitch. You can’t be shouting “best source!” while you’re ignoring anything that might contradict it. And this "Bible math" nonsense? Retard, the chronology is reasoned and supported by accurate historical data, such as Abd al-Rahman’s age. This must be math in the real sense since it will really knock the wings off you, you would rather work with generalized theories rather than stick to facts.
Come back when you learn what debating even is.
