What is the ruling on naming a newborn girl "Touba" after learning that its meaning is a tree in Paradise, and what is the meaning of "Touba" in Surah Ar-Ra'd, Ayah 29: {Those who believe and do righteous deeds - Touba (bliss/goodness) awaits them, and a good return}?

The basic principle regarding names is permissibility unless there is a religious prohibition or a cause for dislike. There is no harm in naming with "Tuba" (طوبى) because it is derived from "tayyib" (good/pure) and it implies optimism for purity and righteousness. Scholars of exegesis have mentioned that the meaning of "Tuba" in the Quran is either a tree in Paradise, or joy and delight, or goodness and bliss, or an honor from Allah, or a name for Paradise itself.
