Will a person marry the same worldly spouse in the Hereafter, or will he marry whomever he loves, or whomever he loved?

If a husband enters Paradise and his wife was righteous, then she will be his wife there. If a woman married more than one husband and all of them entered Paradise, the more probable opinion is that she will be with the last of her husbands in this world. If the man whom the questioner loved did indeed marry her and then died, she has the right to refrain from marrying again, especially if she is not in need of marriage. However, if this beloved person was not her husband, she does not have the right to refrain from marriage, nor do she or her guardian have the right to refuse marriage to a suitable suitor, especially if she fears falling into immorality or is in need of marriage.
