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

(421) And indeed, you have already known the first form of creation (i.e. the creation of Adam): why then do you not remember (or take heed)?

(422) (Saying): "We are indeed Mughramun (i.e. ruined or have lost the money without any profit, or are punished by the loss of all that we spend for cultivation)! (Tafsir Al-Qurtubi)

(423) And verily that is indeed a great oath, if you but know.

(424) That (this) is indeed an honourable recitation (the Noble Qur'an).

(425) And what is the matter with you that you believe not in Allah! While the Messenger (Muhammad صلى الله عليه وسلم) invites you to believe in your Lord (Allah); and He (Allah) has indeed taken your covenant, if you are real believers.

(426) So this Day no ransom shall be taken from you (hypocrites), nor of those who disbelieved, (in the Oneness of Allah - Islamic Monotheism). Your abode is the Fire. That is your maula (friend - proper place), and worst indeed is that destination.

(427) Know that Allah gives life to the earth after its death! indeed We have made clear the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to you, if you but understand.

(428) indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. And We brought forth iron wherein is mighty power (in matters of war ), as well as many benefits for mankind, that Allah may test who it is that will help Him (His religion) and His Messengers in the unseen. Verily, Allah is All-Strong, All-Mighty.

(429) And indeed, We sent Nuh (Noah) and Ibrahim (Abraham), and placed in their offspring Prophethood and Scripture. And among them there are some who are guided; but many of them are Fasiqun (rebellious, disobedient to Allah).

(430) indeed Allah has heard the statement of her (Khaulah bint Tha'labah) that disputes with you (O Muhammad صلى الله عليه وسلم) concerning her husband (Aus bin As-Samit), and complains to Allah. And Allah hears the argument between you both. Verily, Allah is All-Hearer, All-Seer.
