The word(s) "pious" appears 90 time(s) in 88 verse(s) in Quran in Mohsin Khan translation.

(51) And indeed We granted to Musa (Moses) and Harun (Aaron) the criterion (of right and wrong), and a shining light [i.e. the Taurat (Torah)] and a Reminder for Al-Muttaqun (the pious - See V.2:2).

(52) 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).

(53) And indeed We have sent down for you Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that make things plain, and the example of those who passed away before you, and an admonition for those who are Al-Muttaqun (the pious - See V.2:2).

(54) Say: (O Muhammad صلى الله عليه وسلم) "Is that (torment) better or the Paradise of Ete - nity which is promised to the Muttaqun (the pious - See V.2:2)?" It will be theirs as a reward and as a final destination.

(55) And on the Day when He will gather them together and that which they worship besides Allah [idols, angels, pious men, saints] . He will say: "Was it you who misled these My slaves or did they (themselves) stray from the (Right) Path?"

(56) And those who say: "Our Lord! Bestow on us from our wives and our offspring the comfort of our eyes, and make us leaders of the Muttaqun(the pious. See V.2:2)."

(57) And Paradise will be brought near to the Muttaqun (the pious - See V.2:2).

(58) That home of the Hereafter (i.e. Paradise), We shall assign to those who rebel not against the truth with pride and oppression in the land nor do mischief by committing crimes. And the good end is for the Muttaqun (the pious - See V.2:2).

(59) Shall We treat those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds as Mufsidun (those who associate partners in worship with Allah and commit crimes) on earth? Or shall We treat the Muttaqun (the pious - See V.2:2) as the Fujjar (criminals, disbelievers, the wicked)?

(60) This is a Reminder. And verily, for the Muttaqun (the pious - See V.2:2) is a good final return (Paradise),
