Is it permissible to pray for marriage to Houris in Paradise with specific characteristics, and is there any proof for that from the Quran and Sunnah?

Ask Allah for Paradise and seek refuge with Him from Hellfire. For if you attain Paradise, you will attain all that you desire therein, as Allah Almighty says: (They will have therein whatever they desire, abiding eternally), and (and therein is whatever souls desire and [wherein] eyes find delight).

The Salaf [pious predecessors] forbade over-detailing in supplication and asking for specifics concerning Paradise, considering it an act of transgression. It is narrated that Sa’d and Ibn Mughaffal heard their sons making detailed supplications, so they advised them to ask for Paradise and seek refuge from Hellfire, and mentioned the Prophet’s (peace be upon him) saying: "There will be a people who transgress in supplication." It suffices for you to say: "O Allah, I ask You for Paradise and what brings one closer to it of word or deed, and I seek refuge in You from Hellfire and what brings one closer to it of word or deed."
