It is He who shows you lightning, [causing] fear and aspiration, and generates the heavy clouds.
— Saheeh International
It is He who shows you the lightning, inspiring fear and hope; He builds up the clouds heavy with rain;
— M. A. S. Abdel Haleem
It is He Who shows you the lightning, as a fear (for travellers) and as a hope (for those who wait for rain). And it is He Who brings up (or originates) the clouds, heavy (with water).
— Muhammad Muhsin Khan & Muhammad Taqi-ud-Din al-Hilali
