Are there mahrams in Paradise, and who are those forbidden for marriage there?

Maharim (unmarriageable kin) among mothers, daughters, sisters, and paternal aunts, if they are among the pious, will be in Paradise with their righteous relatives, based on the Almighty's saying: "Indeed, the righteous will be in gardens and pleasure" and "And those who believed and whose descendants followed them in faith—We will join their descendants with them." Furthermore, marrying them is forbidden.
