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

(811) And your Lord has decreed that you worship none but Him. And that you be dutiful to your parents. If one of them or both of them attain old age in your life, say not to them a word of disrespect, nor shout at them but address them in terms of honour.

(812) And if you (O Muhammad صلى الله عليه و سلم) turn away from them (kindred, poor, wayfarer whom We have ordered you to give their rights, but if you have no money at the time they ask you for it) and you are awaiting a mercy from your Lord for which you hope, then, speak unto them a soft kind word (i.e. Allah will give me and I shall give you).

(813) And come not near to unlawful sex. Verily, it is a Fahishah (i.e. anything that transgresses its limits: a great sin), and an evil way (that leads one to Hell unless Allah forgives him).

(814) And give full measure when you measure, and weigh with a balance that is straight. That is good (advantageous) and better in the end.

(815) All the bad aspects of these (the above mentioned things) are hateful to your Lord.

(816) This is (part) of Al-Hikmah (wisdom, good manners and high character) which your Lord has revealed to you (O Muhammad صلى الله عليه و سلم). And set not up with Allah any other ilah (god) lest you should be thrown into Hell, blameworthy and rejected, (from Allah's Mercy).

(817) Say (O Muhammad صلى الله عليه و سلم to these polytheists, pagans): "If there had been other alihah (gods) along with Him as they assert, then they would certainly have sought out a way to the Lord of the Throne (seeking His Pleasures and to be near to Him).

(818) And when you (Muhammad صلى الله عليه و سلم) recite the Qur'an, We put between you and those who believe not in the Hereafter, an invisible veil (or screen their hearts, so they hear or understand it not).

(819) Say (O Muhammad صلى الله عليه و سلم) "Be you stones or iron,"

(820) "Or some created thing that is yet greater (or harder) in your breasts (thoughts to be resurrected, even then you shall be resurrected)." Then, they will say: "Who shall bring us back (to life)?" Say: "He Who created you first!" Then, they will shake their heads at you and say: "When will that be?" Say: "Perhaps it is near!"
