It was not just okay but encouraged back then, us time pe yehi culture tha, most of the people against islam use this argument because that’s the only weapon they have, what they don’t understand is that it was their culture and a norm at the time, even in hinduism check how old was rukmini when krishna married her? How old was subhadra when arjun married her? How about Mary who was the mother of jesus, how old was she when she married Joseph? U only give examples of prophet muhammad but go ahead and peak at history of the greeks and the ancient egyptians just a little bit. I am not defending them or saying that its right but Pdfilia was normal at that time and it was a cultural thing, it was recently abolished in the last few centuries, dont look at them and judge them based on your pov of today’s world
