The Qur'an is usually glossed as 'the recitation'. It does not seem to be related to q.r.n 'to grow horns' (denominated from qeren in the sense 'horn') or q.r.n (denominated from qeren in the sense 'ray'). Both verbs are from the same noun qeren 'horn; shofar, ram's horn; strength, power, might; corner, point, peak; ray; damage done by an animal's horn (post-Biblical Hebrew)'. Cognates include: Ugaritic qrn 'horn', qarn 'horn', qurnah 'salient angel', Akkadian qarnu 'horn'. (Seems similar to the Latin cornu 'horn'.) From Klein's dictionary.
