Reddit reply in r/MuslimMarriage: single 30 year olds in the muslim community and — September 25, 2021 | Ali Shukri Amin

Men and women are fundamentally different. Men age in intervals of eight and women in intervals of seven (hence the famous *athar* of 'Ali b. Abi Talib). That being said, the interval of 16-24 lunar years are the most critical for a man, where he is most in need of female companionship. If he misses this period, it can have permanent consequences - hence the number of 20-24 year old brothers freaking out about marriage.

Women are different, they age faster, in intervals of 7. The interval of 28-35 lunar years (26.5-33.5 or so) is the most critical for them, because this is their last chance to easily have a healthy pregnancy.

Hence, most Muslims marry around 26-33 - because that's when the sisters finally decide they need to get married. Whether they realize it or not, there is a deep physiological driver. However, this is a horrible idea.

It is not a good idea for a sister to marry that late as the highest value suitors she has access to are when she is much younger.

Furthermore, men require a lot of upfront investment. For a man to develop and become a formidable candidate, he requires female affection and physicality. Without that, most men fall into deep depression and do not meet their full potential. The refusal of sisters and their families to invest in brothers that have unmet potential, but still a lot of potential, is leading to a lot of brothers that do not measure up to their non-Muslim counterparts (who date and have casual relationships).

If our generation doesn't figure these things out quickly then we will not replace the Muslim population and there won't even be another generation to figure it out.
