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

(181) Or have they a stairway (to heaven), by means of which they listen (to the talks of the angels)? Then let their listener produce some manifest proof.

(182) He has let loose the two seas (the salt and fresh water) meeting together.

(183) On the Day when the hypocrites - men and women - will say to the believers: "Wait for us! let us get something from your light!" It will be said: "Go back to your rear! Then seek a light!" So a wall will be put up between them, with a gate therein. Inside it will be mercy, and outside it will be torment."

(184) Secret counsels (conspiracies) are only from Shaitan (Satan), in order that he may cause grief to the believers. But he cannot harm them in the least, except as Allah permits. And in Allah let the believers put their trust .

(185) O you who believe! Fear Allah and keep your duty to Him. And let every person look to what he has sent forth for the morrow, and fear Allah. Verily, Allah is All-Aware of what you do.

(186) And be not like those who forgot Allah (i.e. became disobedient to Allah), and He caused them to forget their ownselves, (let them to forget to do righteous deeds). Those are the Fasiqun (rebellious, disobedient to Allah).

(187) O you who believe! When believing women come to you as emigrants, examine them; Allah knows best as to their Faith, then if you ascertain that they are true believers send them not back to the disbelievers. They are not lawful (wives) for the disbelievers nor are the disbelievers lawful (husbands) for them. But give them (the disbelievers) that (amount of money) which they have spent [as their Mahr] to them. And there will be no sin on you to marry them if you have paid their Mahr to them. Likewise hold not the disbelieving women as wives, and ask for (the return of) that which you have spent (as Mahr ) and let them (the disbelievers) ask back for that which they have spent. That is the Judgement of Allah, He judges between you. And Allah is All-Knowing, All-Wise.

(188) He it is Who sent among the unlettered ones a Messenger (Muhammad صلى الله عليه وسلم) from among themselves, reciting to them His Verses, purifying them (from the filth of disbelief and polytheism), and teaching them the Book (this Qur'an, Islamic laws and Islamic jurisprudence) and Al-Hikmah (As-Sunnah: legal ways, orders, acts of worship of Prophet Muhammad صلى الله عليه وسلم). And verily, they had been before in manifest error;

(189) O you who believe! let not your properties or your children divert you from the remembrance of Allah. And whosoever does that, then they are the losers.

(190) Allah! La ilaha illa Huwa (none has the right to be worshipped but He). And in Allah (Alone) therefore, let the believers put their trust.
