Al-An'aam (The Cattle)

15. "Say: 'Verily I fear, if I disobey my Lord, the retribution of a grievous Day '."

There are two kinds of fear. The first kind is that sort of awe which is indecent, such as fearing from Holy Struggle. The second kind is that fear which is agreeable and praiseworthy, like fearing from Allah ' punishment.

The Divine Law has been decreed equally for all. Even the Messenger of Allah should fear from its evil, if he sinned.

The fear of the saints of Allah, of course, is for the sake of Allah’s wrath, not from the deities or from people. And, indeed, fear is one of the impedimental factors from deviation and committing wrong.

Regarding to the existence of the Divine completing the argument denoting that the Lord is both the Creator and the Sustainer, and has commanded to submission and prohibited from polytheism, disobedience from the command of Allah deserves punishment.

The verse, addressing the Prophet (S), commands:

"Say: ' Verily I fear, if I disobey my Lord, the retribution of a grievous Day '."
