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

(81) And indeed (many) Messengers before you were mocked at, but their scoffers were surrounded by the very thing that they used to mock at.

(82) Say (O Muhammad صلى الله عليه وسلم): "To whom belongs all that is in the heavens and the earth?" Say: "To Allah. He has prescribed Mercy for Himself. indeed He will gather you together on the Day of Resurrection, about which there is no doubt. Those who have lost themselves will not believe [in Allah as being the only Ilah (God), and Muhammad صلى الله عليه وسلم as being one of His Messengers, and in Resurrection].

(83) Nay, it has become manifest to them what they had been concealing before. But if they were returned (to the world), they would certainly revert to that which they were forbidden. And indeed they are liars.

(84) They indeed are losers who denied their Meeting with Allah, until all of a sudden, the Hour (signs of death) is on them, and they say: "Alas for us that we gave no thought to it," while they will bear their burdens on their backs; and evil indeed are the burdens that they will bear!

(85) We know indeed the grief which their words cause you (O Muhammad صلى الله عليه وسلم): it is not you that they deny, but it is the Verses (the Qur'an) of Allah that the Zalimun (polytheists and wrong-doers) deny.

(86) When he saw the sun rising up, he said: "This is my lord. This is greater." But when it set, he said: "O my people! I am indeed free from all that you join as partners (in worship with Allah).

(87) They are those whom We gave the Book, Al-Hukm (understanding of the religious laws), and Prophethood. But if these disbelieve therein (the Book, Al-Hukm and Prophethood), then, indeed We have entrusted it to a people (such as the Companions of Prophet Muhammad صلى الله عليه وسلم) who are not disbelievers therein.

(88) It is He Who has set the stars for you, so that you may guide your course with their help through the darkness of the land and the sea. We have (indeed) explained in detail Our Ayat (proofs, evidence, verses, lessons, signs, Revelations, etc.) for people who know.

(89) It is He Who has created you from a single person (Adam), and has given you a place of residing (on the earth or in your mother's wombs) and a place of storage [in the earth (in your graves) or in your father's loins]. indeed, We have explained in detail Our revelations (this Qur'an) for people who understand.

(90) Eat not (O believers) of that (meat) on which Allah's Name has not been pronounced (at the time of the slaughtering of the animal), for sure it is Fisq (a sin and disobedience of Allah). And certainly, the Shayatin (devils) do inspire their friends (from mankind) to dispute with you, and if you obey them [by making Al-Maitah (a dead animal) legal by eating it], then you would indeed be Mushrikun (polytheists); [because they (devils and their friends) made lawful to you to eat that which Allah has made unlawful to eat and you obeyed them by considering it lawful to eat, and by doing so you worshipped them; and to worship others besides Allah is polytheism].
