The word(s) "sorrow" appears 13 time(s) in 13 verse(s) in Quran in Mohsin Khan translation.

(1) (Allah) said: "Therefore it (this holy land) is forbidden to them for forty years; in distraction they will wander through the land. So be not sorrowful over the people who are the Fasiqun (rebellious and disobedient to Allah)."

(2) Say (O Muhammad صلى الله عليه وسلم) "O people of the Scripture (Jews and Christians)! You have nothing (as regards guidance) till you act according to the Taurat (Torah), the Injeel (Gospel), and what has (now) been sent down to you from your Lord (the Qur'an)." Verily, that which has been sent down to you (Muhammad صلى الله عليه وسلم) from your Lord increases in most of them (their) obstinate rebellion and disbelief. So be not sorrowful over the people who disbelieve.

(3) So, when they forgot (the warning) with which they had been reminded, We opened for them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them (in punishment), and lo! They were plunged into destruction with deep regrets and sorrows.

(4) Then he (Shu'aib) turned from them and said: "O my people! I have indeed conveyed my Lord's Messages unto you and I have given you good advice. Then how can I sorrow for the disbelieving people's (destruction)."

(5) And he turned away from them and said: "Alas, my grief for Yusuf (Joseph)!" And he lost his sight because of the sorrow that he was suppressing.

(6) He said: "I only complain of my grief and sorrow to Allah, and I know from Allah that which you know not.

(7) So his fruits were encircled (with ruin). And he remained clapping his hands (with sorrow) over what he had spent upon it, while it was all destroyed on its trellises, and he could only say: "Would that I had ascribed no partners to my Lord!" [Tafsir Ibn Kathir]

(8) Then Musa (Moses) returned to his people in a state of anger and sorrow. He said: "O my people! Did not your Lord promise you a fair promise? Did then the promise seem to you long in coming? Or did you desire that wrath should descend from your Lord on you, that you broke your promise to me (i.e disbelieving in Allah and worshipping the calf)?"

(9) Until, when We open for them the gate of severe punishment, then lo! they will be plunged into destruction with deep regrets, sorrows and in despair.

(10) And on the Day when the Hour will be established, the Mujrimun (disbelievers, sinners, criminals, polytheists) will be plunged into destruction with (deep regrets, sorrows, and) despair.
