Job, Elijah, Ezekiel and Enoch
21:83 And [remember] Job, when he called upon his Lord saying: “Affliction has touched me and you are the Most Merciful of the Merciful.”
21:84 And so, We answered him and lifted the affliction which he suffered; and We gave him his people and the like thereof along with them, as a mercy from Us and a Reminder to the worshippers.
In the Koran, Job’s misfortunes are all Satan’s doing.
38:41 And remember Our servant Job when he called out to his Lord: “Satan has visited me with weariness and torture.”
38:42 “Stamp with your foot, and behold, here is a cool washing-place, and water to drink.”
38:43 And we granted to him his family and the like of them also, as a Mercy from Us and a Reminder to people of understanding.
38:44 “And take with your hand a bundle of twigs and strike with it, and do not break your oath.” We have indeed found him steadfast, a blessed servant. He was truly penitent.
Allah, however, has been known to make life miserable for some to see if they will despair of His Mercy; to despair of Allah's Mercy is the second gravest sin, the first being associating other gods with Allah.
11:9 And if We let man have a taste of mercy from Us, then wrest it from him, he yields to despair and becomes ungrateful.
11:10 And if We let him taste prosperity after an adversity has afflicted him, he will say: “Misfortunes have gone away from me”, and becomes joyful and proud.
11:11 Except for those who are patient and do the good deeds; for those are forgiveness and a great reward.
Adversity is just a test, whether it be Allah's or Satan's doing.
2:155 We will certainly test you with some fear and hunger and with some loss of property, lives and crops. Announce the good news to those who endure patiently.
2:156 Those who upon being visited by adversity say: “We are Allah’s [servants] and to Him we shall return.”
2:157 Upon such people are blessings and mercy from their Lord; and those are the well-guided.
37:123 And Elias (Elijah) too was one of the Messengers.
37:124 When he said to his people: “Do you not fear God?
37:125 “Do you call upon Baal (the Phoenician god of fertility), forsaking the Best of Creators,
37:126 “Allah, your Lord and the Lord of your forefathers?”
37:127 But they denounced him as a liar; and behold, they shall be brought forward.
37:128 Except for Our sincere servants.
37:129 And We left him for the later generations;
37:130 “Peace be upon the family of Elias.”
37:131 Thus, We reward the beneficent.
37:132 He is one of our believing servants.
Ezekiel, or Dhul-Kifl, as he is known in the Koran, is mentioned only in passing on two occasions, along with more famous prophets, at the end of both brief accounts of the trials of Job.
21:85 And (remember) Isma’il and Idris and Dhul-Kifl; each was one of the steadfast.
21:86 And We admitted them into Our Mercy; there were all truly righteous.
38:45 And remember Our servants, Abraham, Isaac and Jacob, men of might and perception.
38:46 We have favoured them with the pure trait of remembering the Abode (Paradise).
38:47 They are surely for Us among the well-chosen, the pious.
38:48 And remember Isma’il, Elias and Dhul-Kifl; each was one of the pious.
Praise for Idris, the assumed biblical Enoch, revelation 19:56.
19:51 And [remember] in the Book Moses; he (Moses) was sincere, a Messenger and a Prophet.
19:52 We called him from the right side of the Mount, and brought him closer in communion.
19:53 And We granted him, out of Our Mercy, his brother Aaron, a Prophet.
19:54 And mention in the Book Isma’il; he was true to his promises and was a Messenger and a Prophet.
19:55 He enjoined on his people prayer and almsgiving and was well-pleasing to his Lord.
19:56 And mention in the Book Idris (at times identified with the Biblical Enoch, Wiki); he was truthful and a Prophet.
19:57 And We raised him to a high place.
19:58 Those are the ones whom Allah favoured from among the prophets of the progeny of Adam, of those We carried with Noah, of the progeny of Abraham and Israel (Jacob who was later given the name Israel) and of those We have guided and elected. When the Revelations of the Compassionate were recited to them, they fell down prostrate and weeping.
19:59 Then there came after them a posterity who forgot all about prayer and followed their lusts. They shall face perdition.
19:60 Except for those who repent, believe and do what is right. Those shall enter Paradise and will not be wronged at all.
19:61 Gardens of Eden that the Compassionate has promised His servants in the Unseen. His Promise will certainly be accomplished.
