And among His Signs is this, that He created for you mates from among yourselves, that ye may dwell in tranquillity with them,
and He has put love and mercy between your (hearts): verily in that are Signs for those who reflect.(Qur'an 30:21)
The Prophet said, "A woman is married for four things, i.e., her wealth, her family status, her beauty and her religion. So you should marry the religious woman (otherwise) you will be a losers".
