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

(1561) Or say they: "He (Muhammad صلى الله عليه وسلم) has fabricated it." Say: "If I have fabricated it? still you have no power to support me against Allah. He knows best of what you say among yourselves concerning it (i.e. this Qur'an)! Sufficient is He as a witness between me and you! And He is the Oft-Forgiving, the Most Merciful."

(1562) Say (O Muhammad صلى الله عليه وسلم): "I am not a new thing among the Messengers (of Allah i.e. I am not the first Messenger) nor do I know what will be done with me or with you. I only follow that which is revealed to me, and I am but a plain warner."

(1563) And those who disbelieve (the strong and wealthy) say of those who believe (the weak and poor): "Had it (Islamic Monotheism to which Muhammad صلى الله عليه وسلم is inviting mankind) been a good thing, they (the weak and poor) would not have preceded us thereto!" And when they have not let themselves be guided by it (this Qur'an), they say: "This is an ancient lie!"

(1564) And before this was the Scripture of Musa (Moses) as a guide and a mercy. And this is a confirming Book (the Qur'an) in the Arabic language, to warn those who do wrong, and as glad tidings to the Muhsinun (good-doers. See the footnote of V.9:120).

(1565) Such shall be the dwellers of Paradise, abiding therein (forever) - a reward for what they used to do.

(1566) They are those from whom We shall accept the best of their deeds and overlook their evil deeds. (They shall be) among the dwellers of Paradise - a promise of truth, which they have been promised.

(1567) And remember (Hud) the brother of 'ad, when he warned his people in Al-Ahqaf (the curved sand-hills in the southern part of Arabian Peninsula). And surely, there have passed away warners before him and after him (saying): "Worship none but Allah; truly, I fear for you the torment of a mighty Day (i.e. the Day of Resurrection)."

(1568) And indeed We had firmly established them with that wherewith We have not established you (O Quraish)! And We had assigned them the (faculties of) hearing (ears), seeing (eyes), and hearts; but their hearing (ears), seeing (eyes), and their hearts availed them nothing since they used to deny the Ayat (Allah's Prophets and their Prophethood, proofs, evidence, verses, signs, revelations) of Allah, and they were completely encircled by that which they used to mock at!

(1569) Then why did those whom they had taken for alihah (gods) besides Allah, as a way of approach (to Allah) not help them? Nay, but they vanished completely from them (when there came the torment). And that was their lie, and their inventions which they had been inventing (before their destruction).

(1570) And (remember) when We sent towards you (Muhammad صلى الله عليه وسلم) a group (three to ten persons) of the jinn, (quietly) listening to the Qur'an. When they stood in the presence thereof, they said: "Listen in silence!" And when it was finished, they returned to their people, as warners.
