هُوَ ٱلَّذِى يُرِيكُمُ ٱلْبَرْقَ خَوْفًا وَطَمَعًا وَيُنشِئُ ٱلسَّحَابَ ٱلثِّقَالَ
huwa alladhī yurīkumu l-barqa khawfan waṭamaʿan wayunshi-u l-saḥāba l-thiqāla
It is He who shows you the lightning, inspiring fear and hope; He builds up the clouds heavy with rain;
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).
