The word(s) "assuredly" appears 30 time(s) in 29 verse(s) in Quran in Muhammad Pickthal translation.

(1) assuredly ye will be tried in your property and in your persons, and ye will hear much wrong from those who were given the Scripture before you, and from the idolaters. But if ye persevere and ward off (evil), then that is of the steadfast heart of things.

(2) Except those who seek refuge with a people between whom and you there is a covenant, or (those who) come unto you because their hearts forbid them to make war on you or make war on their own folk. Had Allah willed He could have given them power over you so that assuredly they would have fought you. So, if they hold aloof from you and wage not war against you and offer you peace, Allah alloweth you no way against them.

(3) Had we appointed him (Our messenger) an angel, We assuredly had made him (as) a man (that he might speak to men); and (thus) obscured for them (the truth) they (now) obscure.

(4) And if they had wished to go forth they would assuredly have made ready some equipment, but Allah was averse to their being sent forth and held them back and it was said (unto them): Sit ye with the sedentary!

(5) Most of them follow not but conjecture. assuredly conjecture can by no means take the place of truth. Lo! Allah is Aware of what they do.

(6) assuredly in the Hereafter they will be the greatest losers.

(7) assuredly Allah knoweth that which they keep hidden and that which they proclaim. Lo! He loveth not the proud.

(8) Even if thou (O Muhammad) desirest their right guidance, still Allah assuredly will not guide him who misleadeth. Such have no helpers.

(9) And they assign unto Allah that which they (themselves) dislike, and their tongues expound the lie that the better portion will be theirs. assuredly theirs will be the Fire, and they will be abandoned.

(10) assuredly in the Hereafter they are the losers.
