Is it true that every person gets the spouse they deserve, and that a righteous spouse is granted a righteous partner? And is a fornicator punished by one of his female relatives committing fornication? And does a pious person only marry a pious person, except through a trial from Allah?

The idea that marriage should be between those who are similar in righteousness and corruption is incorrect, and the following indicate this:

1. The story of the wives of Noah and Lot, who were disbelievers, despite their husbands' righteousness. 2. The prohibition in Islamic law against the marriage of an adulterer to a chaste woman and vice versa, which indicates the possibility of such a difference occurring. 3. The Prophet's (peace be upon him) encouragement to marry a woman of religious commitment, which suggests the possibility of a man marrying someone who is not his equal in that regard. 4. The Prophet's (peace be upon him) command to marry those who have religious commitment and good character, which indicates that the opposite might occur.

One should seek a spouse who is religious and of good character, because companionship affects character, as the Prophet (peace be upon him) said: "A man is on the religion of his friend, so let one of you look at whom he befriends." Indeed, characteristics are contagious, and companionship is influential.

As for the punishment of an adulterer through his family, a fabricated hadith (definition) has been reported concerning this, but its meaning may be correct.
