I got banned for just posting on here . Lol <| sep |> I believe it relates to limits of physics getting perfect efficiency given a set fuel typeamount over race distance from an engine of set displacementmaximum rpm primarily , but there would be other parameters that affect this too . <| sep |> no , they ' re weak because scholars studied the chain of transmission and found corruption in them . please stop talking out of your ass buying slaves wasn ' t an issue either . these weren ' t American slaves . Muhammad brought a ton of rights to slaves , and freed literally tens of thousands . he brought slaves all the time to free them . and said people will be rewarded in heaven and have sins forgiven for freeing slaves . Muhammad could not end Slavery , but he made it so slaves could own property , have families , have children born into freedom , buy their freedom , and ended abuse of slaves across the board . lastly , yes , every single Hadith that mentions killing people for leaving Islam has been rejected by all religious leaders for all of Islamic history until the rise of the house of Saud . literally no records show of any Muslim government , king , city state , or popular religious leader imposing this claim . but please , keep spamming lists you dug for hours to find without any context or analysis .
