The word(s) "bad" appears 59 time(s) in 49 verse(s) in Quran in Mohsin Khan translation.

(31) Those who perform As-Salat (Iqamat-as-Salat) and give Zakat and they believe with certainty in the Hereafter (resurrection, recompense of their good and bad deeds, Paradise and Hell).

(32) "O my son! Aqim-As-Salat (perform As-Salat), enjoin (on people) Al-Ma'ruf - (Islamic Monotheism and all that is good), and forbid (people) from Al-Munkar (i.e. disbelief in the Oneness of Allah, polytheism of all kinds and all that is evil and bad), and bear with patience whatever befalls you. Verily, these are some of the important commandments (ordered by Allah with no exemption).

(33) But they turned away (from the obedience of Allah), so We sent against them Sail Al-'Arim (flood released from the dam), and We converted their two gardens into gardens producing bitter bad fruit, and tamarisks, and some few lote-trees.

(34) They say: "Our Lord! Hasten to us Qittana (i.e. our Record of good and bad deeds so that we may see it) before the Day of Reckoning!"

(35) And they will say: "What is the matter with us that we see not men whom we used to count among the bad ones?"

(36) Say: "O 'Ibadi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of Allah: verily, Allah forgives all sins. Truly He is Oft-Forgiving, Most Merciful.

(37) The good deed and the evil deed cannot be equal. Repel (the evil) with one which is better (i.e. Allah orders the faithful believers to be patient at the time of anger, and to excuse those who treat them badly) then verily he, between whom and you there was enmity, (will become) as though he was a close friend.

(38) O you who believe! Let not a group scoff at another group, it may be that the latter are better than the former. Nor let (some) women scoff at other women, it may be that the latter are better than the former. Nor defame one another, nor insult one another by nicknames. How bad is it to insult one's brother after having Faith [i.e. to call your Muslim brother (a faithful believer) as: "O sinner", or "O wicked"]. And whosoever does not repent, then such are indeed Zalimun (wrong-doers, etc.).

(39) Verily, that which you are promised (i.e. Resurrection in the Hereafter and receiving the reward or punishment of good or bad deeds) is surely true.

(40) And that man can have nothing but what he does (good or bad).
