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

(571) And it is not (proper) for the believers to go out to fight (Jihad ) all together. Of every troop of them, a party only should go forth, that they (who are left behind) may get instructions in (Islamic) religion, and that they may warn their people when they return to them, so that they may beware (of evil).

(572) And whenever there comes down a Surah (chapter from the Qur'an), some of them (hypocrites) say: "Which of you has had his Faith increased by it?" As for those who believe, it has increased their Faith, and they rejoice.

(573) But as for those in whose hearts is a disease (of doubt, disbelief and hypocrisy), it will add suspicion and doubt to their suspicion, disbelief and doubt; and they die while they are disbelievers.

(574) Verily, there has come unto you a Messenger (Muhammad صلى الله عليه وسلم) from amongst yourselves (i.e. whom you know well). It grieves him that you should receive any injury or difficulty. He (Muhammad صلى الله عليه وسلم) is anxious over you (to be rightly guided, to repent to Allah, and beg Him to pardon and forgive your sins in order that you may enter Paradise and be saved from the punishment of the Hell-fire); for the believers (he صلى الله عليه وسلم is) full of pity, kind, and merciful.

(575) But if they turn away, say (O Muhammad صلى الله عليه وسلم): "Allah is sufficient for me. La ilaha illa Huwa (none has the right to be worshipped but He) in Him I put my trust and He is the Lord of the Mighty Throne."

(576) Is it a wonder for mankind that We have sent Our Revelation to a man from among themselves (i.e. Prophet Muhammad صلى الله عليه وسلم) (saying): "Warn mankind (of the coming torment in Hell), and give good news to those who believe (in the Oneness of Allah and in His Prophet Muhammad صلى الله عليه وسلم) that they shall have with their Lord the rewards of their good deeds?" (But) the disbelievers say: "This is indeed an evident sorcerer (i.e. Prophet Muhammad صلى الله عليه وسلم and the Qur'an)!

(577) Surely, your Lord is Allah Who created the heavens and the earth in six Days and then rose over (Istawa ) the Throne (really in a manner that suits His Majesty), disposing the affair of all things. No intercessor (can plead with Him) except after His Leave. That is Allah, your Lord; so worship Him (Alone). Then, will you not remember?

(578) It is He Who made the sun a shining thing and the moon as a light and measured out for it stages that you might know the number of years and the reckoning. Allah did not create this but in truth. He explains the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in detail for people who have knowledge.

(579) Verily, those who believe, and do deeds of righteousness, their Lord will guide them through their Faith; under them will flow rivers in the Gardens of Delight (Paradise).

(580) Their way of request therein will be Subhanaka Allahumma (Glory to You, O Allah!) and Salam (peace, safety from evil) will be their greetings therein (Paradise)! and the close of their request will be: Al-Hamdu Lillahi Rabb-il-'Alamin [All the praises and thanks be to Allah, the Lord of 'Alamin (mankind, jinn and all that exists)].
