I havn't found any hadiths regarding the Mother of the Prophet (SAW) or any of his hadiths where he talks about his Mother or Father...
Was she a disbeliever? If not will she reunite with the Prophet (SAW) or anything?
Its kind of discomforting knowing the Mother of the Prophet would be a disbeliever... Allah knows best.
But just imagine Sisters, Allah swt has given you the blessings of Carrying our Beloved Prophet SAW in your Womb. Mashallah what an honour.
