fear of Allah (khawf)

قُلْ إِنِّىٓ أَخَافُ إِنْ عَصَيْتُ رَبِّى عَذَابَ يَوْمٍ عَظِيمٍ

Say, "Indeed I fear, if I should disobey my Lord, the punishment of a tremendous Day."

وَٱلَّذِينَ هُم مِّنْ عَذَابِ رَبِّهِم مُّشْفِقُونَ

And those who are fearful of the punishment of their Lord -

إِنَّا نَخَافُ مِن رَّبِّنَا يَوْمًا عَبُوسًا قَمْطَرِيرًا

Indeed, We fear from our Lord a Day austere and distressful."
