The criteria for selecting the husband are piety and good character, which the Prophet (may the Salah and Salam of Allah be upon him) specified. Abu Hurairah (may Allah be pleased with him) narrated that the Prophet (may the Salah and Salam of Allah be upon him) said: “If someone’s piety and character is acceptable to you, and he asks for the woman [who is under your care] in marriage, accede to his request. If you do not do so, there will be temptation in the earth and vast corruption.” That said, one ought to use the criteria that the Prophet (may the Salah and Salam of Allah be upon him) highlighted, meaning one should marry a man whose piety or religiousness is evident, that being, he should be a person who observes the obligations that Allah ordained and avoid all that which He forbade, and whose character is upright, meaning he has good relations with people, helps them and does not harm them. I advise you to investigate this man, ask about him, and do not simply accept the general praise from people, or accept the words of people who have not known him for a long time.
