In this glorious hadith, Muhammad ensures that humanity goes backwards by reviving a stoning punishment for adultery.
Even though Muhammad says he is closest of anyone to Jesus (Muslim 2365), Muhammad obviously rejects “Let he who is without sin cast the first stone.”
Rather, Muhammad seemingly wants to double down on barbarity. In addition to reviving stoning, Muhammad separately adopts the Arab pagan practice of cutting off hands for theft (Tafsir Ibn Kathir 5:38).
The hadith settles the matter on stoning by stating that Allah, in relation to this incident, revealed:
“And whosoever does not judge by what Allah has revealed, such are the infidels.” (Quran 5:44)
And thus anyone who does not believe in stoning is akafir infidel, doomed to eternal Hell.
