The word(s) "fearful" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) And the Book (one's Record) will be placed (in the right hand for a believer in the Oneness of Allah, and in the left hand for a disbeliever in the Oneness of Allah), and you will see the Mujrimun (criminals, polytheists, sinners), fearful of that which is (recorded) therein. They will say: "Woe to us! What sort of Book is this that leaves neither a small thing nor a big thing, but has recorded it with numbers!" And they will find all that they did, placed before them, and your Lord treats no one with injustice.

(2) Those who believe not therein seek to hasten it, while those who believe are fearful of it, and know that it is the very truth. Verily, those who dispute concerning the Hour are certainly in error far away.

(3) You will see (on the Day of Resurrection), the Zalimun (polytheists and wrong-doers) fearful of that which they have earned, and it (Allah's Torment) will surely befall them. But those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous deeds (will be) in the flowering meadows of the Gardens (Paradise). They shall have whatsoever they desire with their Lord. That is the supreme Grace, (Paradise).

(4) Verily, you (believers in the Oneness of Allah - Islamic Monotheism) are more fearful in their (Jews of Banu An-Nadir) breasts than Allah. That is because they are a people who comprehend not (the Majesty and Power of Allah).
