Criteria to find muslim marriage partner ranges from wealth, beauty, rank, character, congeniality, compatibility to religion. However Islam gives preference to religion out of religion, wealth and beauty.
There are several hadith to help us choose better life partner for us. According to a hadith narrated by Hazrat Abu Hurayrah ,
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 loser.
The characteristic of piety applies to both groom and bride groom and it should be main focus of suitor and woman’s guardian. According to a hadith by At-Tirmidhi , Hazrat Muhamad PBUH said
If someone with whose piety and character you are satisfied comes to you, then marry him. If you do not do so, there will be disorder in the earth and a great deal of evil.
There are many people who appear to be pious muslim in the first look and in reality they leave much to think.
