The word(s) "invoking" appears 8 time(s) in 8 verse(s) in Quran in Mohsin Khan translation.

(1) There is no sin on you if you seek the Bounty of your Lord (during pilgrimage by trading). Then when you leave 'Arafat , remember Allah (by glorifying His Praises, i.e. prayers and invocations) at the Mash'ar-il-Haram . And remember Him (by invoking Allah for all good.) as He has guided you, and verily, you were, before, of those who were astray.

(2) Await they just for the final fullfilment of the event? On the Day the event is finally fulfilled (i.e. the Day of Resurrection), those who neglected it before will say: "Verily, the Messengers of our Lord did come with the truth, now are there any intercessors for us that they might intercede on our behalf? Or could we be sent back (to the first life of the world) so that we might do (good) deeds other than those (evil) deeds which we used to do?" Verily, they have lost their ownselves (i.e. destroyed themselves) and that which they used to fabricate (invoking and worshipping others besides Allah) has gone away from them.

(3) Or lest you should say: "It was only our fathers afortime who took others as partners in worship along with Allah, and we were (merely their) descendants after them; will You then destroy us because of the deeds of men who practised Al-Batil (i.e. polytheism and committing crimes and sins, invoking and worshipping others besides Allah)?" (Tafsir At-Tabari).

(4) And Ibrahim's (Abraham) invoking (of Allah) for his father's forgiveness was only because of a promise he [Ibrahim (Abraham)] had made to him (his father). But when it became clear to him [Ibrahim (Abraham)] that he (his father) is an enemy of Allah, he dissociated himself from him. Verily Ibrahim (Abraham) was Awwah (one who invokes Allah with humility, glorifies Him and remembers Him much) and was forbearing. (Tafsir Al-Qurtubi) .

(5) Verily, Ibrahim (Abraham) was, without doubt, forbearing, used to invoking Allah with humility, and was repentant (to Allah all the time, again and again).

(6) And the fifth (testimony should be) the invoking of the Curse of Allah on him if he be of those who tell a lie (against her).

(7) They used to sleep but little by night [invoking their Lord (Allah) and praying, with fear and hope].

(8) And when the slave of Allah (Muhammad صلى الله عليه وسلم) stood up invoking Him (his Lord - Allah) in prayer they (the jinn) just made round him a dense crowd as if sticking one over the other (in order to listen to the Prophet's recitation).
