Who mention 72!

One day when I was going to copy 過去問(past years Qst)from my Japanese friend and somehow he was asking me about my religious Islam .common question to be asked by a Japanese I think like
“why cannot eat buta(pork)!” or
“Why don’t drink sake, nobody will scold you!”
Huh!! Silly of course!!Those were absolutely prohibited. I couldn’t gave them the best answer n it ended up by telling them that GOD will be mad at me .And it happened to be that we were at the computer’s room and I had introduced this site. Islam no homepage Then here come the topics!! When [A]san opened Wikipedia about Islam and when came to this sentence, he read it loud n LOL!! If I were at their places which is Islam, as a Rome for them or in Japanese it said 珍紛漢紛, maybe I would laugh either, Probably.!Thus it’s not their fault I think but the problem is .
Why free sex with 72 girls!! Why 72!!
Better could just wrote live happily forever, couldn’t` it
There must be a misunderstanding here by the one who wrote this at the 1st place. Want to update it but never did it before. So I beg for those who knew how to , could help to update Wikipedia!
