The word(s) "pit" appears 47 time(s) in 45 verse(s) in Quran in Mohsin Khan translation.

(11) Verily, there has come unto you a Messenger (Muhammad صلى الله عليه وسلم) from amongst yourselves (i.e. whom you know well). It grieves him that you should receive any injury or difficulty. He (Muhammad صلى الله عليه وسلم) is anxious over you (to be rightly guided, to repent to Allah, and beg Him to pardon and forgive your sins in order that you may enter Paradise and be saved from the punishment of the Hell-fire); for the believers (he صلى الله عليه وسلم is) full of pity, kind, and merciful.

(12) And recite to them the news of Nuh (Noah). When he said to his people: "O my people, if my stay (with you), and my reminding (you) of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah is hard on you, then I put my trust in Allah. So devise your plot, you and your partners, and let not your plot be in doubt for you. Then pass your sentence on me and give me no respite.

(13) By no means will they escape (from Allah's Torment) on earth, nor have they protectors besides Allah! Their torment will be doubled! They could not bear to hear (the preachers of the truth) and they used not to see (the truth because of their severe aversion, in spite of the fact that they had the sense of hearing and sight).

(14) With Him (Allah). So plot against me, all of you, and give me no respite.

(15) Then, when they entered unto him [Yusuf (Joseph)], they said: "O ruler of the land! A hard time has hit us and our family, and we have brought but poor capital, so pay us full measure and be charitable to us. Truly, Allah does reward the charitable."

(16) They ask you to hasten the evil before the good, while (many) exemplary punishments have indeed occurred before them. But verily, your Lord is full of Forgiveness for mankind in spite of their wrong-doing. And verily, your Lord is (also) Severe in punishment.

(17) And indeed (many) Messengers were mocked at before you (O Muhammad صلى الله عليه و سلم), but I granted respite to those who disbelieved, and finally I punished them. Then how (terrible) was My punishment!

(18) Their Messengers said: "What! Can there be a doubt about Allah, the Creator of the heavens and the earth? He calls you (to Monotheism and to be obedient to Allah) that He may forgive you of your sins and give you respite for a term appointed." They said: "You are no more than human beings like us! You wish to turn us away from what our fathers used to worship. Then bring us a clear authority (i.e. a clear proof of what you say)."

(19) Consider not that Allah is unaware of that which the Zalimun (polytheists, wrong-doers) do, but He gives them respite up to a Day when the eyes will stare in horror.

(20) And warn (O Muhammad صلى الله عليه و سلم) mankind of the Day when the torment will come unto them; then the wrong-doers will say: "Our Lord! Respite us for a little while, we will answer Your Call and follow the Messengers!" (It will be said): "Had you not sworn aforetime that you would not leave (the world for the Hereafter).
