I have read some hadiths that the Prophet Muhammad will marry Mary, the mother of Jesus, in heaven (and the wife of Pharaoh) are these authentic?
I couldn't find the exact reference only to the books they are supposedly recorded in.
Muhammad said, “In heaven, Mary mother of Jesus, will be one of my wives.” al-Suyuti (6/395) (WikiIslam.net)
and
"The Messenger of God ... said, ‘God married me in paradise to Mary the daughter of 'Imran and to the wife of Pharaoh and the sister of Moses.’" Tabarani
The WikiIslam.net reference for this says: Ibn Kathir, Qisas al-Anbiya [Cairo: Dar al-Kutub, 1968/1388], p. 381- as cited in Aliah Schleifer's Mary The Blessed Virgin of Islam [Fons Vitae; ISBN: 1887752021; July 1, 1998], p. 64;
