(The thunder hymneth His praise) by His command; it is an angel; it is also said: it is the voice of the sky (and (so do) the angels) and also the angels hymn His praise (for awe of Him) the angels have awe towards Allah. (He launcheth the thunder bolts) i.e. fire (and smiteth with them whom He will) He destroys by means of fire whoever He will, referring here to Zayd Ibn Qays whom Allah destroyed by fire, along with his friend 'Amir Ibn al-Tufayl who was killed as a result of being stabbed in his waist (while they dispute (in doubt) concerning Allah) while they dispute with Muhammad (pbuh) concerning the Religion of Allah, (and He is mighty in wrath) His chastisement is severe.
