The word(s) "indeed" appears 320 time(s) in 310 verse(s) in Quran in Abdullah Yusuf Ali translation.

(81) "But those ye call upon besides Him, are unable to help you, and indeed to help themselves."

(82) If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)!

(83) If Allah had found in them any good. He would indeed have made them listen: (As it is), if He had made them listen, they would but have turned back and declined (Faith).

(84) Remember how they said: "O Allah if this is indeed the Truth from Thee, rain down on us a shower of stones form the sky, or send us a grievous penalty."

(85) The Signs of Allah have they sold for a miserable price, and (many) have they hindered from His way: evil indeed are the deeds they have done.

(86) O ye who believe! there are indeed many among the priests and anchorites, who in Falsehood devour the substance of men and hinder (them) from the way of Allah. And there are those who bury gold and silver and spend it not in the way of Allah: announce unto them a most grievous penalty-

(87) If ye help not (your leader), (it is no matter): for Allah did indeed help him, when the Unbelievers drove him out: he had no more than one companion; they two were in the cave, and he said to his companion, "Have no fear, for Allah is with us": then Allah sent down His peace upon him, and strengthened him with forces which ye saw not, and humbled to the depths the word of the Unbelievers. But the word of Allah is exalted to the heights: for Allah is Exalted in might, Wise.

(88) If there had been immediate gain (in sight), and the journey easy, they would (all) without doubt have followed thee, but the distance was long, (and weighed) on them. They would indeed swear by Allah, "If we only could, we should certainly have come out with you": They would destroy their own souls; for Allah doth know that they are certainly lying.

(89) indeed they had plotted sedition before, and upset matters for thee, until,- the Truth arrived, and the Decree of Allah became manifest much to their disgust.

(90) Among them is (many) a man who says: "Grant me exemption and draw me not into trial." Have they not fallen into trial already? and indeed Hell surrounds the Unbelievers (on all sides).
