How sound are the verses that describe the light of a woman's incisors in Paradise as an indication of the varying degrees of women based on their faith, and does this contradict the texts mentioned regarding the number of Houris?

These verses from Ibn al-Qayyim's "Nuniyyah" describe the Houris (maidens of Paradise), incorporating what is mentioned in authentic evidence from the Quran and Hadith. Among these are the words of Allah Almighty: "And Houris (beautiful, fair females) with wide, lovely eyes Like unto preserved pearls" [Quran, al-Waqi'ah 56:22-23], and what is stated in Sahih al-Bukhari about the description of the people of Paradise, that each man among them will have two wives, the marrow of whose shins will be visible from behind their flesh due to their beauty.
