The word(s) "ad" appears 2687 time(s) in 1984 verse(s) in Quran in Mohsin Khan translation.

(331) And they prevent others from him (from following Prophet Muhammad صلى الله عليه وسلم) and they themselves keep away from him, and (by doing so) they destroy not but their ownselves, yet they perceive (it) not.

(332) Nay, it has become manifest to them what they had been concealing before. But if they were returned (to the world), they would certainly revert to that which they were forbidden. And indeed they are liars.

(333) If you could but see when they will be held (brought and made to stand) in front of their Lord! He will say: "Is not this (Resurrection and the taking of the accounts) the truth?" They will say: "Yes, by our Lord!" He will then say: "So taste you the torment because you used not to believe."

(334) We know indeed the grief which their words cause you (O Muhammad صلى الله عليه وسلم): it is not you that they deny, but it is the Verses (the Qur'an) of Allah that the Zalimun (polytheists and wrong-doers) deny.

(335) Verily, (many) Messengers were denied before you (O Muhammad صلى الله عليه وسلم), but with patience they bore the denial, and they were hurt; till Our Help reached them, and none can alter the Words (Decisions) of Allah. Surely there has reached you the information (news) about the Messengers (before you).

(336) If their aversion (from you, O Muhammad صلى الله عليه وسلم and from that with which you have been sent) is hard on you, (and you cannot be patient of their harm to you), then if you were able to seek a tunnel in the earth or a ladder to the sky, so that you may bring them a sign (and you cannot do it, so be patient). And had Allah willed, He could have gathered them together (all) on true guidance, so be not you one of those who are Al-Jahilun (the ignorant).

(337) It is only those who listen (to the Message of Prophet Muhammad صلى الله عليه وسلم), will respond (benefit from it), but as for the dead (i.e. disbelievers), Allah will raise them up, then to Him they will be returned (for their recompense).

(338) Say (O Muhammad صلى الله عليه وسلم): "Tell me if Allah's Torment comes upon you, or the Hour comes upon you, would you then call upon any one other than Allah? (Reply) if you are truthful!"

(339) Verily, We sent (Messengers) to many nations before you (O Muhammad صلى الله عليه وسلم). And We seized them with extreme poverty (or loss in wealth) and loss in health (with calamities) so that they might humble themselves (believe with humility).

(340) When Our Torment reached them, why then did they not humble themselves (believe with humility)? But their hearts became hardened, and Shaitan (Satan) made fair-seeming to them that which they used to do.
