The word(s) "grieve" appears 42 time(s) in 41 verse(s) in Quran in Mohsin Khan translation.

(11) You shall certainly be tried and tested in your wealth and properties and in your personal selves, and you shall certainly hear much that will grieve you from those who received the Scripture before you (Jews and Christians) and from those who ascribe partners to Allah; but if you persevere patiently, and become Al-Muttaqun (the pious - See V.2:2) then verily, that will be a determining factor in all affairs (and that is from the great matters which you must hold on with all your efforts).

(12) O Messenger (Muhammad صلى الله عليه وسلم)! Let not those who hurry to fall into disbelief grieve you, of such who say: "We believe" with their mouths but their hearts have no faith. And of the Jews are men who listen much and eagerly to lies - listen to others who have not come to you. They change the words from their places; they say, "If you are given this, take it, but if you are not given this, then beware!" And whomsoever Allah wants to put in Al-Fitnah [error, because of his rejecting of Faith], you can do nothing for him against Allah. Those are the ones whose hearts Allah does not want to purify (from disbelief and hypocrisy); for them there is a disgrace in this world, and in the Hereafter a great torment.

(13) Surely, those who believe (in the Oneness of Allah, in His Messenger Muhammad صلى الله عليه وسلم and all that was revealed to him from Allah), and those who are the Jews and the Sabians and the Christians, - whosoever believed in Allah and the Last Day, and worked righteousness, on them shall be no fear, nor shall they grieve.

(14) And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve.

(15) O Children of Adam! If there come to you Messengers from amongst you, reciting to you My Verses, then whosoever becomes pious and righteous, on them shall be no fear nor shall they grieve.

(16) Are they those, of whom you swore that Allah would never show them mercy. (Behold! It has been said to them): "Enter Paradise, no fear shall be on you, nor shall you grieve."

(17) And when Musa (Moses) returned to his people, angry and grieved, he said: "What an evil thing is that which you have done (i.e. worshipping the calf) during my absence. Did you hasten and go ahead as regards the matter of your Lord (you left His worship)?" And he threw down the Tablets and seized his brother by (the hair of) his head and dragged him towards him. Harun (Aaron) said: "O son of my mother! Indeed the people judged me weak and were about to kill me, so make not the enemies rejoice over me, nor put me amongst the people who are Zalimun (wrong-doers)."

(18) If good befalls you (O Muhammad صلى الله عليه وسلم), it grieves them, but if a calamity overtakes you, they say: "We took our precaution beforehand" and they turn away rejoicing.

(19) Verily, there has come unto you a Messenger (Muhammad صلى الله عليه وسلم) from amongst yourselves (i.e. whom you know well). It grieves him that you should receive any injury or difficulty. He (Muhammad صلى الله عليه وسلم) is anxious over you (to be rightly guided, to repent to Allah, and beg Him to pardon and forgive your sins in order that you may enter Paradise and be saved from the punishment of the Hell-fire); for the believers (he صلى الله عليه وسلم is) full of pity, kind, and merciful.

(20) No doubt! Verily, the Auliya' of Allah [i.e. those who believe in the Oneness of Allah and fear Allah much (abstain from all kinds of sins and evil deeds which he has forbidden), and love Allah much (perform all kinds of good deeds which He has ordained)], no fear shall come upon them nor shall they grieve.
