The first thing we should look for when marrying is how committed the person is to Islam. Prophet Muhammad (sallallahu alayhi was sallam) said, "A woman is normally sought as a wife for her wealth, beauty, nobility, or religiousness (adherence to Islam), but choose a religious woman and you will prosper. " (Muslim) And he said, "A woman is married for four things, i.e., her wealth, her family status, her beauty and her religion. You should marry the religious woman (otherwise) you will be a loser. "(Bukhari) And he said, "The whole world is a provision, and the best object of benefit of the world is the pious woman. " (Muslim)

The same holds true when looking for a husband, as the Messenger of Allah (sallallahu alayhi was sallam) said, "When someone with whose religion and character you are satisfied asks to marry your daughter, comply with his request. If you do not do so, there will be corruption and great evil on earth. " (Tirmidhi)

Of course, both parties have to agree to marry one another and they can not be forced to marry one another . The Messenger of Allah (sallallahu alayhi was sallam) said, "A woman whom has been previously married has more right concerning herself than her guardian, and a virgin's consent must be asked about herself..." (Bukhari and Muslim)
