Chapter: Excellence of contracting marriage with a pious lady.

Abu Huraira (Allah be pleased with him) reported Allah’s Messenger (May peace be upon him) as saying: A woman may be married for four reasons: for her property, her status, her beauty and her religion, so try to get one who is religious, may your hand be besmeared with dust.
