The word(s) "let" appears 241 time(s) in 215 verse(s) in Quran in Mohsin Khan translation.

(11) And perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad صلى الله عليه وسلم), the Hajj and 'Umrah (i.e. the pilgrimage to Makkah) for Allah. But if you are prevented (from completing them), sacrifice a Hady (animal, i.e. a sheep, a cow, or a camel) such as you can afford, and do not shave your heads until the Hady reaches the place of sacrifice. And whosoever of you is ill or has an ailment in his scalp (necessitating shaving), he must pay a Fidyah (ransom) of either observing Saum (fasts) (three days) or giving Sadaqah (charity - feeding six poor persons) or offering sacrifice (one sheep). Then if you are in safety and whosoever performs the 'Umrah in the months of Hajj before (performing) the Hajj, (i.e. Hajj-at-Tamattu' and Al-Qiran), he must slaughter a Hady such as he can afford, but if he cannot afford it, he should observe Saum (fasts) three days during the Hajj and seven days after his return (to his home), making ten days in all. This is for him whose family is not present at Al-Masjid-Al-Haram (i.e. non-resident of Makkah). And fear Allah much and know that Allah is Severe in punishment.

(12) The mothers shall give suck to their children for two whole years, (that is) for those (parents) who desire to complete the term of suckling, but the father of the child shall bear the cost of the mother's food and clothing on a reasonable basis. No person shall have a burden laid on him greater than he can bear. No mother shall be treated unfairly on account of her child, nor father on account of his child. And on the (father's) heir is incumbent the like of that (which was incumbent on the father). If they both decide on weaning, by mutual consent, and after due consultation, there is no sin on them. And if you decide on a foster suckling-mother for your children, there is no sin on you, provided you pay (the mother) what you agreed (to give her) on reasonable basis. And fear Allah and know that Allah is All-Seer of what you do.

(13) O you who believe! When you contract a debt for a fixed period, write it down. let a scribe write it down in justice between you. let not the scribe refuse to write as Allah has taught him, so let him write. let him (the debtor) who incurs the liability dictate, and he must fear Allah, his Lord, and diminish not anything of what he owes. But if the debtor is of poor understanding, or weak, or is unable to dictate for himself, then let his guardian dictate in justice. And get two witnesses out of your own men. And if there are not two men (available), then a man and two women, such as you agree for witnesses, so that if one of them (two women) errs, the other can remind her. And the witnesses should not refuse when they are called (for evidence). You should not become weary to write it (your contract), whether it be small or big, for its fixed term, that is more just with Allah; more solid as evidence, and more convenient to prevent doubts among yourselves, save when it is a present trade which you carry out on the spot among yourselves, then there is no sin on you if you do not write it down. But take witnesses whenever you make a commercial contract. let neither scribe nor witness suffer any harm, but if you do (such harm), it would be wickedness in you. So be afraid of Allah; and Allah teaches you. And Allah is the All-Knower of each and everything.

(14) And if you are on a journey and cannot find a scribe, then let there be a pledge taken (mortgaging) ; then if one of you entrust the other, let the one who is entrusted discharge his trust (faithfully), and let him be afraid of Allah, his Lord. And conceal not the evidence for he, who hides it, surely his heart is sinful. And Allah is All-Knower of what you do.

(15) Alif-Lam-Mim. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings].

(16) (They say): "Our Lord! let not our hearts deviate (from the truth) after You have guided us, and grant us mercy from You. Truly, You are the Bestower."

(17) let not the believers take the disbelievers as Auliya (supporters, helpers) instead of the believers, and whoever does that will never be helped by Allah in any way, except if you indeed fear a danger from them. And Allah warns you against Himself (His punishment) , and to Allah is the final return.

(18) Then whoever disputes with you concerning him ['Îsa (Jesus)] after (all this) knowledge that has come to you [i.e. 'Îsa (Jesus) being a slave of Allah, and having no share in Divinity], say: (O Muhammad صلى الله عليه وسلم) "Come, let us call our sons and your sons, our women and your women, ourselves and yourselves - then we pray and invoke (sincerely) the Curse of Allah upon those who lie."

(19) O you who believe! Fear Allah (by doing all that He has ordered and by abstaining from all that He has forbidden) as He should be feared. [Obey Him, be thankful to Him, and remember Him always], and die not except in a state of Islam [as Muslims (with complete submission to Allah)].

(20) let there arise out of you a group of people inviting to all that is good (Islam), enjoining Al-Ma'ruf (i.e. Islamic Monotheism and all that Islam orders one to do) and forbidding Al-Munkar (polytheism and disbelief and all that Islam has forbidden). And it is they who are the successful.
