﴿ ٱلَّذِينَ يَخْشَوْنَ رَبَّهُم بِٱلْغَيْبِ وَهُم مِّنَ ٱلسَّاعَةِ مُشْفِقُونَ ﴾

“who stand in awe of their Sustainer although He is beyond the reach of human perception, and who tremble at the thought of the Last Hour.”

(Those who fear their Lord) those who work for their Lord (in secret) even if He is invisible to them (and who dread the Hour) and who dread the chastisement of the Last Day.
