The video you linked has uh, let’s say a lot of problems The first red flag being that the individual claims that ‘he is more knowledgeable about islam than anybody else’ which is a major red flag, but let’s put that aside for now

The very first hadith he quotes is da’eef (weak) so that is pretty much irrelevant considering there are sahih(correct) contradictory hadith(s) one of them being this Riyad as-Salihin 1390 https://sunnah.com/riyadussalihin:1390 (Sahih)(Correct), this hadith specifically mentions religious knowledge, and doesn’t specify who gets this knowledge or not

But he uses the weak hadith to push his point anyway, and the reason is because the feeling i get is that this guy is trying to say we should not share any of our knowledge with people of other faiths

Second issue he mentions is that women are not allowed to come to colleges with non mehrams and not learn anything that takes them away from islam and uses it as the reason girls are not supposed to study in Islam, what he conveniently misses out though is that men are also subject to these rulings, and i don’t think men have any problem going to colleges, flip this guy from atheist to religious and this is the type of guy who would ban women from education, I think i don’t need to explain the mentality this guy has, also there is a thing called ‘concessions’ which are granted by scholars, and most of the (decent) scholars are of the opinion that studying in co-ed schools and colleges is permissible as long both the sides stay within the prescribed rulings

Third: This guy picks a random guys book who I have never heard of and starts quoting whatever he has written, safe to say i don't care what ‘Ashraf Ali Thanvi’ has to say, he never seems to derive any of his opinions from quran and sunnah, i have already mentioned that no society is perfect, while I have never even seen the book, let alone heard this guys name, I will admit that there maybe some places where this guy is popular, and I will wholeheartedly admit that this is a problem, the source of sharia is hadith and quran, and ijma (see the last part) (and to some extent the four imam’s of fiqh) anyone who starts saying whatever they think is best/appropriate is dishonest

Then at 15:50, he says the most ridiculous thing possible, he shows a fatwa where IT CLEARLY STATES THAT IT IS PERMISSIBLE FOR HER TO STUDY IF THERE ARE NO ALTERNATIVES and then he proceeds to ask what if these laws are not met, what laws are not met? I don't know about any college that forces male and female people to sit together, or make them talk forcefully, because if something like that exists, it is an issue on a state level, people are given freedom of expression, no women (or men) should be forced to do anything.

He then proceeds to say the prophet only took help from women in those things which the women were able to do, what? How can someone do something they can’t do, the statement doesn’t even make sense, this was really the point where I was about to close the video but then he said some other things that i think could be clarified, you can learn more about women treating men in battle here: https://www.islamweb.net/en/fatwa/156919/the-life-of-rufaydah-al-aslamiyyah

His argument about The university of qarawiyyin is also so ignorant it’s hilarious, he didn’t even bother to read the Wikipedia page which clearly states that there is lack of documentation about who used to study there and what type of studies were there, regardless if it’s fake or not, he used this to try to prove his point anyway, if you dig deeper into wiki you will find this:

Students were male, but traditionally it has been said that "facilities were at times provided for interested women to listen to the discourse while accommodated in a special gallery (riwaq) overlooking the scholars' circle". Like I said, that there is a lack of documentation, so really anything is to be taken with a grain of salt, it also shows that there was period of decline until the early 1900’s meaning there were probably fewer students, it was finally reformed in the early-mid 1900s until it was finally integrated into the state educational system in 1947, and women have been studying there since 1940’s.

Overall this is just a pathetic source when you are trying to prove something.

I would also like to add that a hypothesis is not given by a conducting one experiment, a lot of factors are taken into account and the experiment is repeated multiple times with different conditions, similarly picking one ayah from the quran and using it to prove a point doesn’t make a lot of sense, you need look at the context, and the other verses and hadiths as well, which i have already provided a few and you can look for more yourself, or if you want I can list them, which will take a lot of time on my side

The next slave girl concept has been long obliterated in today’s modern world, you have to remember like i said in my previous comment, quran also has a lot of laws for the arabs of that time which have been called illiterate a variety of times, people really used to marry practically infinite amount of women and even their mothers, there are many hadiths that talk about releasing slaves and how rewarding it is ^[1][2][3]^ in fact it is a compensation in many cases where you miss important religious duties, to the point where the system has died (i am not saying Islam did it, it happened due to a variety of reasons)

Also even in that time you just couldn’t make any girl a slave, this was only for the prisoners of war, you were supposed to share your food and wealth with them and help them in tough works, I am not saying that having a slave is even remotely justified today, but what i am saying is that there is a lot more nuance to it

Also in response to some other replies, I am not really trying to influence or change your opinion, you are absolutely entitled to your opinions, I am just writing this to speak about how many muslims I see who are discriminated by people because of terrorist organizations or an incomplete understanding of Islam, even if you don’t agree with the teachings, it doesn’t even remotely justify people using terrible words and accusing them of actions they didn’t do in the first place, not just about islam, i could make a similar case about judaism, christianity or any other religion for that matter.

Some people need to start seeing other people as people first not muslim/christian/jew/atheist
