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

(1791) Say (O Muhammad صلى الله عليه وسلم): "The knowledge (of its exact time) is with Allah only, and I am only a plain warner."

(1792) But when they will see it (the torment on the Day of Resurrection) approaching, the faces of those who disbelieve will change and turn black with sadness and in grief and it will be said (to them): "This is (the promise) which you were calling for!"

(1793) Say (O Muhammad صلى الله عليه وسلم): "Tell me! If Allah destroys me, and those with me, or He bestows His Mercy on us - who can save the disbelievers from a painful torment?"

(1794) Say (O Muhammad صلى الله عليه وسلم): "Tell me! If (all) your water were to sink away, who then can supply you with flowing (spring) water?"

(1795) You (O Muhammad صلى الله عليه وسلم), by the Grace of your Lord, are not mad.

(1796) And Verily, for you (O Muhammad صلى الله عليه وسلم) will be an endless reward.

(1797) And Verily, you (O Muhammad صلى الله عليه وسلم) are on an exalted (standard of) character.

(1798) Which of you is afflicted with madness.

(1799) So (O Muhammad صلى الله عليه وسلم) obey you not the deniers [(of Islamic Monotheism - those who belie the Verses of Allah), the Oneness of Allah, and the Messengership of Muhammad صلى الله عليه وسلم]

(1800) And (O Muhammad صلى الله عليه وسلم) obey you not everyone Hallaf Mahin (the one who swears much and is a liar or is worthless). [Tafsir At-Tabari]
