The word(s) "bad" appears 22 time(s) in 20 verse(s) in Quran in Muhammad Pickthal translation.

(1) Warfare is ordained for you, though it is hateful unto you; but it may happen that ye hate a thing which is good for you, and it may happen that ye love a thing which is bad for you. Allah knoweth, ye know not.

(2) O ye who believe! Spend of the good things which ye have earned, and of that which We bring forth from the earth for you, and seek not the bad (with intent) to spend thereof (in charity) when ye would not take it for yourselves save with disdain; and know that Allah is Absolute, Owner of Praise.

(3) All food was lawful unto the Children of Israel, save that which Israel forbade himself, (in days) before the Torah was revealed. Say: Produce the Torah and read it (unto us) if ye are truthful.

(4) Allah had already given you the victory at badr, when ye were contemptible. So observe your duty to Allah in order that ye may be thankful.

(5) Give unto orphans their wealth. Exchange not the good for the bad (in your management thereof) nor absorb their wealth into your own wealth. Lo! that would be a great sin.

(6) And (also) those who spend their wealth in order to be seen of men, and believe not in Allah nor the Last Day. Whoso taketh Satan for a comrade, a bad comrade hath he.

(7) And We caused the Mount to tower above them at (the taking of) their covenant: and We bade them: Enter the gate, prostrate! and We bode them: Transgress not the Sabbath! and We took from them a firm covenant.

(8) Because of the wrongdoing of the Jews We forbade them good things which were (before) made lawful unto them, and because of their much hindering from Allah's way,

(9) Unto those who are Jews We forbade every animal with claws. And of the oxen and the sheep forbade We unto them the fat thereof save that upon the backs or the entrails, or that which is mixed with the bone. That we awarded them for their rebellion. And lo! we verily are truthful.

(10) Say: Come, bring your witnesses who can bear witness that Allah forbade (all) this. And if they bear witness, do not thou bear witness with them. Follow thou not the whims of those who deny Our revelations, those who believe not in the Hereafter and deem (others) equal with their Lord.
