The word(s) "successful" appears 42 time(s) in 42 verse(s) in Quran in Mohsin Khan translation.

(21) And she, in whose house he was, sought to seduce him (to do an evil act), and she closed the doors and said: "Come on, O you." He said: "I seek refuge in Allah (or Allah forbid)! Truly, he (your husband) is my master! He made my living in a great comfort! (So I will never betray him). Verily, the Zalimun (wrong and evil-doers) will never be successful."

(22) "For, if they come to know of you, they will stone you (to death or abuse and harm you) or turn you back to their religion; and in that case you will never be successful."

(23) "So devise your plot, and then assemble in line. And whoever overcomes this day will be indeed successful."

(24) "And throw that which is in your right hand! It will swallow up that which they have made. That which they have made is only a magician's trick, and the magician will never be successful, to whatever amount (of skill) he may attain."

(25) O you who have believed! Bow down, and prostrate yourselves, and worship your Lord and do good that you may be successful.

(26) successful indeed are the believers.

(27) Then, those whose scales (of good deeds) are heavy, they are the successful.

(28) Verily I have rewarded them this Day for their patience: they are indeed the ones that are successful.

(29) And whoever invokes (or worships), besides Allah, any other ilah (god), of whom he has no proof; then his reckoning is only with his Lord. Surely! Al-Kafirun (the disbelievers in Allah and in the Oneness of Allah, polytheists, pagans, idolaters) will not be successful.

(30) And tell the believing women to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts) and not to show off their adornment except only that which is apparent (like both eyes for necessity to see the way, or outer palms of hands or one eye or dress like veil, gloves, head-cover, apron, etc.), and to draw their veils all over Juyubihinna (i.e. their bodies, faces, necks and bosoms) and not to reveal their adornment except to their husbands, or their fathers, or their husband's fathers, or their sons, or their husband's sons, or their brothers or their brother's sons, or their sister's sons, or their (Muslim) women (i.e. their sisters in Islam), or the (female) slaves whom their right hands possess, or old male servants who lack vigour, or small children who have no sense of feminine sex. And let them not stamp their feet so as to reveal what they hide of their adornment. And all of you beg Allah to forgive you all, O believers, that you may be successful.
