Musa (alayhis salam) would have never married the daughter of the man who gave him shelter, if his father in-law’s conditions were based on material possession like today. At that time, he had no club memberships, money, cars or other luxurious items, he wasn’t even given Prophet hood yet! He was a modest man and a righteous spouse. That was all he had. But for the wise, that’s the true wealth, the real criteria.
