Are my wife's grandmother's sister and my husband's grandfather's sister forbidden to me (in marriage)?

The wife's grandmother, whether from the father's or mother's side, is permanently forbidden to her husband merely upon contracting the marriage with her granddaughter, because she is considered among "your wives' mothers." As for the sister of the wife's grandmother, she is temporarily forbidden to the husband as long as the wife is under his marital bond. It is permissible to marry her after the wife's death or divorce and the completion of her waiting period (iddah). Similarly, the sister of the wife's grandfather is temporarily forbidden to him, as she is considered like the wife's paternal aunt. The Hadith explicitly states the impermissibility of combining a woman with her paternal aunt or her maternal aunt.
