A Muslim & Muslimah have a nikah and agree upon a mahr that is to be met in 30 days [i.e. a used car], but during this brief period he discovers things about her Deen that he totally disagrees with and she also begins to see defects in his character and Deen. They are both unhappy right now, Talaq happens, but the question at hand is:
Is the mahr still mandatory upon him to give her, though they both are heading towards Talaq?
A Hadith and/or Fatawa of the Ulama are acceptable.Text
