The word(s) "lay" appears 72 time(s) in 69 verse(s) in Quran in Mohsin Khan translation.

(31) And you might have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the midst of the Cave. That is (one) of the Ayat (proofs, evidence, signs) of Allah. He whom Allah guides, he is the rightly guided; but he whom He sends astray, for him you will find no Wali (guiding friend) to lead him (to the right Path).

(32) There (on the Day of Resurrection), Al-Walayah (protection, power, authority and kingdom) will be for Allah (Alone), the True God. He (Allah) is the Best for reward and the Best for the final end. (La ilaha illallah- none has the right to be worshipped but Allah).

(33) So make no haste against them; We only count out to them a (limited) number (of the days of the life of this world and delay their term so that they may increase in evil and sins).

(34) Comes not unto them an admonition (a chapter of the Qur'an) from their Lord as a recent revelation but they listen to it while they play

(35) We created not the heavens and the earth and all that is between them for a (mere) play.

(36) They said: "Have you brought us the truth, or are you one of those who play about?"

(37) And indeed We created man (Adam) out of an extract of clay (water and earth).

(38) No nation can advance their term, nor can they delay it.

(39) "Did you think that We had created you in play (without any purpose), and that you would not be brought back to Us?"

(40) Or [the state of a disbeliever] is like the darkness in a vast deep sea, overwhelmed with waves topped by waves, topped by dark clouds, (layers of) darkness upon darkness: if a man stretches out his hand, he can hardly see it! And he for whom Allah has not appointed light, for him there is no light.
