Re: Muhammad (SAW) and his wives
Mary(pbud) gave birth to Jesus(pbuh) at the age of 12., Joseph the husband was 90.
That tells you some thing was different physically back then.
On top abu bakar(as) was influential man.. he would not give her daughter away in unreasonable marriage.
Now think about this..
back then girls did not have to finish uni..
people die with tooth infections… during travels etc…
Strength came from more son, and men it tribe.
Put those factors together, would a father keep her daughter till the age of 25 , before he marry her? OR would they put her in circle of life as soon as girls are ready ?
