I never knew Muhammed succumbed to that particular piece of ignorance before, but if that was the only thing I knew about him, that would be enough to show me that his revelations weren't being guided by any God.
He was just an ignorant man from an ignorant era.
Maybe then ,we should spread thw word amongst some left handed Muslims or Muslim parents of left handed kids, or Muslims who've been forced to write with their right hands, & suffered due to it in whatever way. You never know
what exactly is the key to opening the floodgates of doubt for believing Muslims.
My mom's cousin was herself a daughter of first cousins & married her second cousin who too was the son of first cousins, both their sons suffer from genetic abnormalities. This "aunt" of mine says that she no longer believes in Islam today, once she blindly accepted that the Quran contains scientific miracles-now she knows that its a book written by
an ignorant man(the same term you used) who got his daughter Fatima married to his cousin Ali & set a bad precedent for Muslims-whose children are saddled with birth defects as a consequence of blindly believing in Muhammad's sunnah.
Since you wouldn't have believed in Muhammad's revelations coming from the Almighty had you known that he subscribed to this ancient superstition, some Muslims, particularly some rationalist left handed ones,hopefully might cease believing ...
But at least it is a harmless ritual.
Not so harmless for left handed kids forced to write with their right hands or rebuked for doing anything with their left hands, I know a Muslim boy around 9 whose parents tied his left hand to his body & made him write with his right hand, as thats' what Muhammad taught, the boy continued to wet his bed & was sullen, withdrawn & unhappy, until a psychiatrist convinced his parents to stop this bulls***. Today, he's happily left handed, eats & writes with his left hand.
Why demonize left handedness, a naturally occuring phenomenon, by connecting it to Satan?
