The word(s) "lawful" appears 83 time(s) in 58 verse(s) in Quran in Mohsin Khan translation.

(41) And indeed We have honoured the Children of Adam, and We have carried them on land and sea, and have provided them with At-Tayyibat (lawful good things), and have preferred them above many of those whom We have created with a marked preferment.

(42) Likewise, We awakened them (from their long deep sleep) that they might question one another. A speaker from among them said: "How long have you stayed (here)?" They said: "We have stayed (perhaps) a day or part of a day." They said: "Your Lord (Alone) knows best how long you have stayed (here). So send one of you with this silver coin of yours to the town, and let him find out which is the good lawful food, and bring some of that to you. And let him be careful and let no man know of you.

(43) (Saying) eat of the Tayyibat (good lawful things) wherewith We have provided you, and commit no transgression or oppression therein, lest My Anger should justly descend on you. And he on whom My Anger descends, he is indeed perished. [Tafsir At-Tabari]

(44) That (Manasik- prescribed duties of Hajj is the obligation that mankind owes to Allah), and whoever honours the sacred things of Allah, then that is better for him with his Lord. The cattle are lawful to you, except those (that will be) mentioned to you (as exceptions). So shun the abomination (worshipping) of idol, and shun lying speech (false statements) -

(45) O (you) Messengers! Eat of the Tayyibat [all kinds of Halal foods which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables, fruits, etc.] and do righteous deeds. Verily! I am Well-Acquainted with what you do.

(46) (This is) a Surah (chapter of the Qur'an) which We have sent down and which We have enjoined, (ordained its laws); and in it We have revealed manifest Ayat (proofs, evidence, verses, lessons, signs, revelations - lawful and unlawful things, and set boundaries of Islamic Religion), that you may remember.

(47) We have indeed sent down (in this Qur'an) manifest Ayat (proofs, evidence, verses, lessons, signs, revelations, lawful and unlawful things, and the set boundaries of Islamic religion, etc. that make things clear showing the Right Path of Allah). And Allah guides whom He wills to the Straight Path (i.e. to Allah's religion of Islamic Monotheism).

(48) And (remember) Lut (Lot)! When he said to his people. Do you commit Al-Fahishah (evil, great sin, every kind of unlawful sexual intercourse, sodomy) while you see (one another doing evil without any screen)?"

(49) "But seek, with that (wealth) which Allah has bestowed on you, the home of the Hereafter, and forget not your portion of lawful enjoyment in this world; and do good as Allah has been good to you, and seek not mischief in the land. Verily, Allah likes not the Mufsidun (those who commit great crimes and sins, oppressors, tyrants, mischief-makers, corrupters)."

(50) Recite (O Muhammad صلى الله عليه وسلم) what has been revealed to you of the Book (the Qur'an), and perform As-Salat (Iqamat-as-Salat). Verily, As-Salat (the prayer) prevents from Al-Fahsha' (i.e. great sins of every kind, unlawful sexual intercourse) and Al-Munkar (i.e. disbelief, polytheism, and every kind of evil wicked deed) and the remembering (praising) of (you by) Allah (in front of the angels) is greater indeed [than your remembering (praising) of Allah in prayers. And Allah knows what you do.
