The word(s) "indeed" appears 481 time(s) in 466 verse(s) in Quran in Mohsin Khan translation.

(371) Enter the gates of Hell to abide therein: and (indeed) what an evil abode of the arrogant!

(372) And, indeed We have sent Messengers before you (O Muhammad صلى الله عليه وسلم): of some of them We have related to you their story. And of some We have not related to you their story, and it was not given to any Messenger that he should bring a sign except by the Leave of Allah. But, when comes the Commandment of Allah, the matter will be decided with truth, and the followers of falsehood will then be lost.

(373) When the Messengers came to them, from before them and behind them (saying): "Worship none but Allah", they said: "If our Lord had so willed, He would surely have sent down the angels. So indeed we disbelieve in that with which you have been sent."

(374) And We have assigned for them (devils) intimate companions (in this world), who have made fair-seeming to them, what was before them (evil deeds which they were doing in the present worldly life and disbelief in the Reckoning and the Resurrection) and what was behind them (denial of the matters in the coming life of the Hereafter as regards punishment or reward). And the Word (i.e. the torment) is justified against them as it was justified against those who were among the previous generations of jinn and men that had passed away before them. indeed they (all) were the losers.

(375) And among His Signs (in this), that you see the earth barren; but when We send down water (rain) to it, it is stirred to life and growth (of vegetations). Verily, He Who gives it life, surely, is Able to give life to the dead (on the Day of Resurrection). indeed He is Able to do all things.

(376) And indeed We gave Musa (Moses) the Scripture, but dispute arose therein. And had it not been for a Word that went forth before from your Lord, (the torment would have overtaken them) and the matter would have been settled between them. But truly, they are in grave doubt thereto (i.e. about the Qur'an). [Tafsir Al-Qurtubi].

(377) And indeed whosoever takes revenge after he has suffered wrong, for such there is no way (of blame) against them.

(378) And thus We have sent to you (O Muhammad صلى الله عليه و سلم) Ruh (a Revelation, and a Mercy) of Our Command. You knew not what is the Book, nor what is Faith? But We have made it (this Qur'an) a light wherewith We guide whosoever of Our slaves We will. And verily, you (O Muhammad صلى الله عليه و سلم) are indeed guiding (mankind) to the Straight Path (i.e. Allah's Religion of Islamic Monotheism).

(379) And verily, it (this Qur'an) is in the Mother of the Book (i.e. Al-Lauh Al-Mahfuz), with Us, indeed exalted, full of wisdom.

(380) And indeed if you ask them, "Who has created the heavens and the earth?" They will surely say: "The All-Mighty, the All-Knower created them."
