Thanks for sharing but there seems to be a number of errors in this link you have shared. For example, one of the main arguments is that "the only times it can possibly mean a literal hit/strike is when the preposition "bi" (with/by) is used." but this is incorrect as we see in other verses such as 812"When your Lord revealed to the angels I am with you, therefore make firm those who believe. I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike (idrub) off every fingertip of them." there is no preposition or "bi" here but it is a literal hit/strike.
Is this an error or have I got it wrong?
Thanks!
