Translation of the verse 87 from Surah Al-Anbiya’ : Number of verses 112 - - page 329 - Part 17.
And (remember) Dhan-Nun (Jonah), when he went off in anger, and imagined that We shall not punish him (i.e. the calamites which had befallen him)! But he cried through the darkness (saying): La ilaha illa Anta [none has the right to be worshipped but You (O Allah)], Glorified (and Exalted) are You [above all that (evil) they associate with You]. Truly, I have been of the wrong-doers."
And [mention] the man of the fish, when he went off in anger and thought that We would not decree [anything] upon him. And he called out within the darknesses, "There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers."
(21:87) And We showed a favour to Zun-nun *82 Remember when he went away in anger *83 for he thought that We would not take him to task for this. *84 But afterwards he invoked Us from the depths of darkness, *85 saying, "There is no God but Thou: glory be to Thee: I had indeed committed a wrong".
*82) That is, Jonah. Literally Zun-Nun means `the man of the fish". He was called so because he was devoured by a fish by the Command of AIIah. (Also See XXXV11:142 and X:98 and its E.N.'s 98-100).
*83) Prophet Jonah left his people before he received Allah's Command for migration.
*84) He presumed that he should leave, the place which was going to be visited by the scourge of Allah. This was not by itself an offence but it was an offence for a Prophet to leave the place of his Mission without the permission of Allah.
*85) "....darkness": the darkness in the belly of the fish and the darkness of the sea over and above it.
