The word(s) "certainly" appears 107 time(s) in 101 verse(s) in Quran in Abdullah Yusuf Ali translation.

(61) And if indeed thou ask them who it is that sends down rain from the sky, and gives life therewith to the earth after its death, they will certainly reply, "Allah!" Say, "Praise be to Allah!" But most of them understand not.

(62) And those who strive in Our (cause),- We will certainly guide them to our Paths: For verily Allah is with those who do right.
