Up in the mountains around Salalah is a mosque compound containing the grave (supposedly) of Nabi Ayub. Christians will recognize him as Job, the Biblical prophet who endured unimaginable suffering at the hands of Satan and still refused to curse or deny God. In the Bible, Job is an existential book that ultimately affirms faith in an ultimate Creator. The Quran mentions his name on numerous occasions, including this ayat:
(21:83)"And (remember) Ayub, when he cried to his Lord, "Truly distress has seized me, But Thou art the Most Merciful of those that are Merciful."
