All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallahu ‘alayhi wa sallam, is His slave and Messenger.
There are some reported ahaadeeth saying that Maryam, the daughter of ‘Imraan, and Aasiyyah, the wife of Pharaoh, shall be among the wives of our Prophet, sallallahu ‘alayhi wa sallam, in Paradise. Scholars of Hadeeth criticized the chains of narration of those reports. Please refer to fatwa in Paradise">82924.
Hence, it is impermissible for the Muslim to ask Allah to make them his wives in Paradise because this constitutes transgression in supplication, which is prohibited. Allah, The Exalted, says (what means): {Call upon your Lord in humility and privately; indeed, He does not like transgressors.} [Quran 7:55]
Transgression in supplication includes asking for what is impossible according to the Sharia or innate human disposition. Asking to marry Maryam or Aasiyyah, may Allah exalt their mention, is impossible if they will be among the wives of the Prophet, sallallahu ‘alayhi wa sallam, in Paradise.
Allah knows best.
