When someone whose religion and character you are pleased with comes to you then marry (her to) him.
Abu Hatim Al-Muzani, may Allah be pleased with him, narrated that:
The Messenger of Allah, may the peace and blessings of Allah be upon him, said: "When someone whose religion and character you are pleased with comes to you then marry (her to) him. If you do not do so, then there will be turmoil (Fitnah) in the land and discord (Fasad). If you do not do so, then there will be turmoil (Fitnah) in the land and discord (Fasad)." They said: "O Messenger of Allah! What if there was something about him?" He said: "When someone whose religion and character you are pleased with comes to you then marry ( her to ) him." (And he, may the peace and blessings of Allah be upon him, said this) three times.
If one is to marry, he must choose a spouse who is religiously committed. It is okay to choose a woman of good lineage, wealthy and beautiful. One must be heedful of the fact that the religious commitment is the standard according to which any other thing would be accepted or rejected.
On the other hand, the woman should choose the religiously committed man who has good morals. This man is like a treasure if he likes her he would honor her. Otherwise, if he disliked her, he would not wrong her.
Her guardian must marry her from a man who has the meanings of manhood and is really competent for her as explained in this Hadith.
We know that man is responsible for and supervisor over the woman. The one who is not religiously committed and whose character is not accepted will not be able to maintain her rights and preserve her religion? A dissolute man is a misfortune for his wife, regardless of his superiority over many other men. If this dissolute man is rich, his wealth would tempt him to indulge in the evils openly in front of the family, neighbors and friends. Even though he may have good lineage and prestigious status, the dissolute would continue to be a source of harm for those who know him, and those who do not know him.
The jurists have considered efficiency to be a requirement of the valid marriage, in the sense that men are competent for women in religion and character, there is no difference between them in that, and they differed concerning other qualifications.
It is permissible for a woman to marry a man who is less than her in terms of the prestigious status and wealth as long as he is a righteous man of a good character.
If the man is not religiously committed, the pride guardian has the right to reject his proposal.
In addition to what is mentioned above, this commandment entails that the lineage is not a condition for the validity of marriage. Unless the man is of too low lineage that will dishonor the wife, or be a reason to bring shame on the wife.
It is noteworthy that religiously commitment overwhelms poverty, old age, ugliness, and so on.
We conclude from this commandment that we should stick to humbleness before Allah in all matters, and that we should treat people humbly as long as this way does not entail harm.
