Whether the basmala counts as a verse in its own right is a genuine and old legal disagreement among the schools of Islamic law, not a marginal curiosity. The Shafii school holds that it is the first verse of the Fatiha and must be recited aloud within it in prayer, while the Hanafi school holds that it is a separator placed between suras rather than a numbered verse of whichever sura follows it, and reciters trained in the two schools will audibly recite prayer differently as a direct result of this centuries old dispute, which has never been resolved into a single practice across Sunni Islam. The sole exception to the basmala opening a sura, Sura 9, is itself explained by classical commentators through a tradition holding that the Prophet did not specify where its placement should be at the point the Quran was compiled, leaving a small but stable irregularity in an otherwise near universal pattern.
Rahman and rahim share the same triliteral root, connected in classical Arabic lexicography to the word for a womb, and translating them as near synonyms, most merciful and most compassionate, is common but considered by many classical commentators to understate a real distinction. Al Tabari and other early exegetes read al rahman as mercy extended to the whole of creation without exception, believer and unbeliever alike in this life, and al rahim as mercy specific to believers, particularly in the hereafter, so the two words are read as differing in scope rather than simply in intensity, a distinction most English translations, forced to choose between two near identical adjectives, cannot easily preserve.
