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

(341) So, when they forgot (the warning) with which they had been reminded, We opened for them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them (in punishment), and lo! They were plunged into destruction with deep regrets and sorrows.

(342) And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve.

(343) But those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), the torment will touch them for their disbelief (and for their belying the Message of Muhammad صلى الله عليه وسلم). [Tafsir Al-Qurtubi].

(344) Say (O Muhammad صلى الله عليه وسلم): "I don't tell you that with me are the treasures of Allah, nor (that) I know the Unseen; nor I tell you that I am an angel. I but follow what is revealed to me." Say: "Are the blind and the one who sees equal? Will you not then take thought?"

(345) Say (O Muhammad صلى الله عليه وسلم): "I have been forbidden to worship those whom you invoke (worship) besides Allah." Say: "I will not follow your vain desires. If I did, I would go astray, and I would not be one of the rightly guided."

(346) Say (O Muhammad صلى الله عليه وسلم): "I am on clear proof from my Lord (Islamic Monotheism), but you deny it (the truth that has come to me from Allah). I have not gotten what you are asking for impatiently (the torment). The decision is only for Allah, He declares the truth, and He is the Best of judges."

(347) Say: "If I had that which you are asking for impatiently (the torment), the matter would have been settled at once between me and you, but Allah knows best the Zalimun (polytheists and wrong-doers)."

(348) He is the Irresistible, (Supreme) over His slaves, and He sends guardians (angels guarding and writing all of one's good and bad deeds) over you, until when death approaches one of you, Our Messengers (angel of death and his assistants) take his soul, and they never neglect their duty.

(349) Say (O Muhammad صلى الله عليه وسلم): "Who rescues you from the darkness of the land and the sea (dangers like storms), (when) you call upon Him in humility and in secret (saying): If He (Allah) only saves us from this (danger), we shall truly be grateful."

(350) Say (O Muhammad صلى الله عليه وسلم): "Allah rescues you from this and from all (other) distresses, and yet you worship others besides Allah."
