The word(s) "certainly" appears 476 time(s) in 417 verse(s) in Quran in Muhammad Habib Shakir translation.

(381) And certainly he warned them of Our violent seizure, but they obstinately disputed the warning.

(382) And certainly they endeavored to turn him from his guests, but We blinded their eyes; so taste My chastisement and My warning.

(383) And certainly a lasting chastisement overtook them in the morning.

(384) And certainly We have made the Quran easy for remembrance, but is there anyone who will mind?

(385) And certainly the warning came to Firon's people.

(386) And certainly We have already destroyed the likes of you, but is there anyone who will mind?

(387) And certainly you know the first growth, why do you not then mind?

(388) If We pleased, We should have certainly made it broken down into pieces, then would you begin to lament:

(389) certainly We sent Our apostles with clear arguments, and sent down with them the Book and the balance that men may conduct themselves with equity; and We have made the iron, wherein is great violence and advantages to men, and that Allah may know who helps Him and His apostles in the secret; surely Allah is Strong, Mighty.

(390) And certainly We sent Nuh and Ibrahim and We gave to their offspring the (gift of) prophecy and the Book; so there are among them those who go aright, and most of them are transgressors.
