The word(s) "cruel" appears 3 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And if a woman fears cruelty or desertion on her husband's part, there is no sin on them both if they make terms of peace between themselves; and making peace is better. And human inner-selves are swayed by greed. But if you do good and keep away from evil, verily, Allah is Ever Well-Acquainted with what you do.

(2) Is it then he who laid the foundation of his building on piety to Allah and His Good Pleasure better, or he who laid the foundation of his building on the brink of an undetermined precipice ready to crumble down, so that it crumbled to pieces with him into the Fire of Hell. And Allah guides not the people who are the Zalimun (cruel, violent, proud, polytheist and wrong-doer).

(3) cruel, and moreover base-born (of illegitimate birth).
