The word(s) "disease" appears 13 time(s) in 12 verse(s) in Quran in Muhammad Pickthal translation.

(1) In their hearts is a disease, and Allah increaseth their disease. A painful doom is theirs because they lie.

(2) And thou seest those in whose heart is a disease race toward them, saying: We fear lest a change of fortune befall us. And it may happen that Allah will vouchsafe (unto thee) the victory, or a commandment from His presence. Then will they repent them of their secret thoughts.

(3) When the hypocrites and those in whose hearts is a disease said: Their religion hath deluded these. Whoso putteth his trust in Allah (will find that) lo! Allah is Mighty, Wise.

(4) But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers.

(5) That He may make that which the devil proposeth a temptation for those in whose hearts is a disease, and those whose hearts are hardened - Lo! the evil-doers are in open schism -

(6) Is there in their hearts a disease, or have they doubts, or fear they lest Allah and His messenger should wrong them in judgment? Nay, but such are evil-doers.

(7) And when the hypocrites, and those in whose hearts is a disease, were saying: Allah and His messenger promised us naught but delusion.

(8) O ye wives of the Prophet! Ye are not like any other women. If ye keep your duty (to Allah), then be not soft of speech, lest he in whose heart is a disease aspire (to you), but utter customary speech.

(9) If the hypocrites, and those in whose hearts is a disease, and the alarmists in the city do not cease, We verily shall urge thee on against them, then they will be your neighbours in it but a little while.

(10) And those who believe say: If only a surah were revealed! But when a decisive surah is revealed and war is mentioned therein, thou seest those in whose hearts is a disease looking at thee with the look of men fainting unto death. Therefor woe unto them!
