The word(s) "capable" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) And marry those among you who are single (i.e. a man who has no wife and the woman who has no husband) and (also marry) the Salihun (pious, fit and capable ones) of your (male) slaves and maid-servants (female slaves). If they be poor, Allah will enrich them out of His Bounty. And Allah is All-Sufficient for His creatures' needs, All-Knowing (about the state of the people).

(2) (They) belied all Our Signs, so We seized them with a Seizure of the All-Mighty, All-capable (Omnipotent).
