Quote:
{13:12} It is He who shows you lightening, [causing] fear and aspiration, and generates the heavy clouds.
Excellent translation.
Quote:
{13:13} And the thunder exalts [God] with praise of Him - and the angels [as well] from fear of Him - and He sends thunderbolts and strikes therewith whom He wills while they dispute about God; and He is severe in assault.
I suggest,
{13:13} And the thunder sanctifies [God] with praise of Him - and the angels [as well] out of fear of Him - and He sends thunderbolts and strikes therewith whom He wills, and they dispute about God and He is string in means.
