Praise be to
does not matter, and it does not matter if the woman is older or if
the husband is older. The Prophet
(peace and blessings of Allaah be upon him) married Khadeejah when she
was forty and he was twenty-five. What does matter is that the man should
look for a righteous woman who is religiously-committed, even if she
is older than him, if she is still young enough to bear children. The
point is that age should not be a problem and such a marriage is not
wrong if the man is righteous and the woman is righteous. May Allaah
guide us all to the best way.
