The word(s) "truly" appears 138 time(s) in 136 verse(s) in Quran in Mohsin Khan translation.

(61) Or that He may catch them with gradual wasting (of their wealth and health). truly! Your Lord is indeed full of Kindness, Most Merciful?

(62) And Allah has created you and then He will cause you to die; and of you there are some who are sent back to senility, so that they know nothing after having known (much). truly! Allah is All-Knowing, All-Powerful.

(63) So put not forward similitudes for Allah (as there is nothing similar to Him, nor He resembles anything). truly! Allah knows and you know not.

(64) And to Allah belongs the Unseen of the heavens and the earth. And the matter of the Hour is not but as a twinkling of the eye, or even nearer. truly! Allah is Able to do all things.

(65) Invite (mankind, O Muhammad صلى الله عليه و سلم) to the Way of your Lord (i.e. Islam) with wisdom (i.e. with the Divine Revelation and the Qur'an) and fair preaching, and argue with them in a way that is better. truly, your Lord knows best who has gone astray from His Path, and He is the Best Aware of those who are guided.

(66) truly, Allah is with those who fear Him (keep their duty unto Him), and those who are Muhsinun (good-doers. See the footenote of V.9:120).

(67) truly, your Lord enlarges the provision for whom He wills and straitens (for whom He wills). Verily, He is Ever All-Knower, All-Seer of His slaves.

(68) The seven heavens and the earth and all that is therein, glorify Him and there is not a thing but glorifies His Praise. But you understand not their glorification. truly, He is Ever Forbearing, Oft-Forgiving.

(69) Your Lord is He Who drives the ship for you through the sea, in order that you may seek of His Bounty. truly He is Ever Most Merciful towards you.

(70) And they say: "Glory be to our Lord! truly, the Promise of our Lord must be fulfilled."
