Regarding your, uh, reference to the Prophet Muhammad and one of his wives, Aisha bint Abi Bakr. According to some traditional Hadiths (which, just in case you weren't aware, are sayings and actions of the Prophet that were compiled after his death), particularly Sahih Bukhari and Sahih Muslim, it is reported that he was betrothed to Aisha when she was 6 and they consummated the marriage when she was 9. This is commonly picked up, as you've done, in certain circles to criticize Muhammad personally and thus Islam in general.
However, the accuracy of this age is disputed among both Muslim and secular scholars because there are some apparent logical contradictions in timelines between the various accounts, so estimates of the true age (and discussions about the explanations of the context) vary depending on who you talk to. You'd probably have to read up a fair bit, speak to some knowledgeable practising Muslims and consult the works of a few historians who specialize in the field if you want to know more. It's a pretty complex topic.
(But I wouldn't recommend ever showing them this, uh, image. Might not quite get the constructive reception you'd like if you do... Pretty offensive to any believing Muslim, putting that *extremely* mildly. ⚠️🥶🙈 Or anyone with religious or more (small c) conservative Christian sensibilities for that matter. NSFW on steroids. I'm not a believer so I can deal with it.)

PS The goat thing above/below is presumably the usual highly sophisticated (/s) racial stereotype of Arabs and their supposed preference for attraction to livestock. (Again, I wouldn't recommend showing that to (m)any Arabs or people with Middle Eastern roots, unless you know them very well and are 100% confident they have a sense of humour that will be okay with that. Otherwise, I'm not your bodyguard lol. Good luck.)
