The word(s) "truly" appears 170 time(s) in 163 verse(s) in Quran in Abdullah Yusuf Ali translation.

(101) truly that is just and fitting,- the mutual recriminations of the People of the Fire!

(102) Say: "truly am I a Warner: no god is there but the one Allah, Supreme and Irresistible,-

(103) Is it not to Allah that sincere devotion is due? But those who take for protectors other than Allah (say): "We only serve them in order that they may bring us nearer to Allah." truly Allah will judge between them in that wherein they differ. But Allah guides not such as are false and ungrateful.

(104) If ye reject (Allah), truly Allah hath no need of you; but He liketh not ingratitude from His servants: if ye are grateful, He is pleased with you. No bearer of burdens can bear the burden of another. In the end, to your Lord is your Return, when He will tell you the truth of all that ye did (in this life). for He knoweth well all that is in (men's) hearts.

(105) Say: "O ye my servants who believe! Fear your Lord, good is (the reward) for those who do good in this world. Spacious is Allah's earth! those who patiently persevere will truly receive a reward without measure!"

(106) "Serve ye what ye will besides him." Say: "truly, those in loss are those who lose their own souls and their People on the Day of Judgment: Ah! that is indeed the (real and) evident Loss!

(107) Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? Then He causes to grow, therewith, produce of various colours: then it withers; thou wilt see it grow yellow; then He makes it dry up and crumble away. truly, in this, is a Message of remembrance to men of understanding.

(108) truly thou wilt die (one day), and truly they (too) will die (one day).

(109) But it has already been revealed to thee,- as it was to those before thee,- "If thou wert to join (gods with Allah), truly fruitless will be thy work (in life), and thou wilt surely be in the ranks of those who lose (all spiritual good)".

(110) They will say: "Praise be to Allah, Who has truly fulfilled His Promise to us, and has given us (this) land in heritage: We can dwell in the Garden as we will: how excellent a reward for those who work (righteousness)!"
