Way to go to justify barbarism in order to keep women in check. There is no need to go back to the Muslim califate. That's like shooting yourself into both feet in order to lose weight.
The West had a far superior system up until roughly the 1930s and in some countries beyond that. You had wives - honorable women - and you had sluts/hookers. Honorable women did not go with a man on their own, never went alone with him anywhere and married early.
Obviously modern systems would need adaptations, but it can be done if sane healthy models were promoted. This can be done without throwing a towel over them relentlessly and wiping out their clitoris which contributes to different behavior, weight gain and even a form of eternal frustration in many.
As most things imagined by Islam - it's just retarded.
Keep the family strong - marry in the family with your cousins and uncles. - You end up with a literally dumber weaker population vs to what it could be.
Keep the old traditions strong - burn and destroy all infidel knowledge, the Quran is the only book you know. You end up with knowledge barely being done and the entire Muslim world publishing as many books as one mid-sized European country - nevermind patent generation and other achievements.
Have polygamy and female restraint which necessities eternal warfar and constant supply of slaves - since you cannto have that becasu the West has become too strong = rampant homosexuality in countries like Saudi Arabia where many bottom class men fuck powerbottoms and consider themselves not gay. (and they may not be - they are just victims in a prison system called Islam)
In reality the wide majority of Western girls even in the 1950s or for Eastern European countries up to the 1970s wasn't as degenerate as advertised. The cultural marxism and aggressive promotion of degeneration, slut-pushing vs slut-shaming - all began with the 70s, but accelerated in the 80s and 90s - resulting in the 00s Tinder-super-power-mode. It runs counter the inherent female instincts. It takes one war and one shitlord totalitarian ruler to promote sane values again.
