The Quran uses marid as an adjective before it is ever a proper class name, describing any jinn who defies the order set over creation, most memorably one pelted by a flung star for eavesdropping on the celestial assembly. That single image, a rebellious spirit caught listening where it should not, is nearly everything scripture itself says about the word. Its transformation into a fixed rank within a graded hierarchy of jinn, stronger than an ordinary jinni, stronger even than an ifrit, happened later and outside the Quran entirely, carried by centuries of Arabic storytelling in which a marid guards sunken treasure, holds a besieged city under a curse, or must be captured in a bottle and sealed with the seal of Solomon before it will grant anything at all. One Thousand and One Nights did more than any single text to fix this picture in the popular imagination, and it is worth being honest about the layering involved: the Quran gives the word its moral weight, defiance against a right order, while the folk tradition gives it its rank, its habitat and its bargaining behavior. Neither layer erases the other. A reader who meets marid only in translation of the Nights is meeting the folk layer; a reader who meets it only in tafsir is meeting the scriptural layer; the creature as popularly known today is both at once, and classical commentators themselves already drew on pre-Islamic Arabian belief in jinn when they explained the term, so the class was never purely invented by later storytellers, only elaborated by them.
