The word(s) "disobedient" appears 52 time(s) in 50 verse(s) in Quran in Mohsin Khan translation.

(31) And they belied them (those Ayat) wrongfully and arrogantly, though their ownselves were convinced thereof [i.e. those (Ayat ) are from Allah, and Musa (Moses) is the Messenger of Allah in truth, but they disliked to obey Musa (Moses), and hated to believe in his Message of Monotheism]. So see what was the end of the Mufsidun (disbelievers, disobedient to Allah, evil-doers and liars.).

(32) "Put your hand in your bosom, it will come forth white without a disease; and draw your hand close to your side to be free from the fear (which you suffered from the snake, and also your hand will return to its original state). These are two Burhans (signs, miracles, evidence, proofs) from your Lord to Fir'aun (Pharaoh) and his chiefs. Verily, they are the people who are Fasiqun (rebellious, disobedient to Allah).

(33) But if they answer you not (i.e. do not bring the Book nor believe in your doctrine of Islamic Monotheism), then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah? Verily Allah guides not the people who are Zalimun (wrong-doers, disobedient to Allah, and polytheists).

(34) And when Our Messengers came to Ibrahim (Abraham) with the glad tidings they said: "Verily, we are going to destroy the people of this [Lut (Lot's)] town (i.e. the town of Sodom in Palestine); truly, its people have been Zalimun [wrong-doers, polytheists disobedient to Allah, and who belied their Messenger Lut (Lot)]."

(35) Is then he who is a believer like him who is a Fasiq (disbeliever and disobedient to Allah)? Not equal are they.

(36) And as for those who are Fasiqun (disbelievers and disobedient to Allah), their abode will be the Fire, every time they wish to get away therefrom, they will be put back thereto, and it will be said to them: "Taste you the torment of the Fire which you used to deny."

(37) Certainly, that is how We deal with Al-Mujrimun (polytheists, sinners, disbelievers, criminals, the disobedient to Allah).

(38) This is so! And for the Taghun (transgressors, the disobedient to Allah and His Messenger - disbelievers in the Oneness of Allah, criminals) will be an evil final return (Fire).

(39) Thus he [Fir'aun (Pharaoh)] befooled (and misled) his people, and they obeyed him. Verily, they were ever a people who were Fasiqun (rebellious, disobedient to Allah).

(40) We created them not except with truth (i.e. to examine and test those who are obedient and those who are disobedient and then reward the obedient ones and punish the disobedient ones), but most of them know not.
