The word(s) "worse" appears 9 time(s) in 7 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And when you said: O Musa! we cannot bear with one food, therefore pray Lord on our behalf to bring forth for us out of what the earth grows, of its herbs and its cucumbers and its garlic and its lentils and its onions. He said: Will you exchange that which is better for that which is worse? Enter a city, so you will have what you ask for. And abasement and humiliation were brought down upon them, and they became deserving of Allah's wrath; this was so because they disbelieved in the communications of Allah and killed the prophets unjustly; this was so because they disobeyed and exceeded the limits.

(2) Then your hearts hardened after that, so that they were like rocks, rather worse in hardness; and surely there are some rocks from which streams burst forth, and surely there are some of them which split asunder so water issues out of them, and surely there are some of them which fall down for fear of Allah, and Allah is not at all heedless of what you do.

(3) And let not those deem, who are niggardly in giving away that which Allah has granted them out of His grace, that it is good for them; nay, it is worse for them; they shall have that whereof they were niggardly made to cleave to their necks on the resurrection day; and Allah's is the heritage of the heavens and the earth; and Allah is aware of what you do.

(4) Say: Shall I inform you of (him who is) worse than this in retribution from Allah? (worse is he) whom Allah has cursed and brought His wrath upon, and of whom He made apes and swine, and he who served the Shaitan; these are worse in place and more erring from the straight path.

(5) And certainly We have created for hell many of the jinn and the men; they have hearts with which they do not understand, and they have eyes with which they do not see, and they have ears with which they do not hear; they are as cattle, nay, they are in worse errors; these are the heedless ones.

(6) And when Our clear communications are recited to them you will find denial on the faces of those who disbelieve; they almost spring upon those who recite to them Our communications. Say: Shall I inform you of what is worse than this? The fire; Allah has promised it to those who disbelieve; and how evil the resort!

(7) (As for) those who shall be gathered upon their faces to hell, they are in a worse plight and straying farther away from the path.
