Surah 38. Sad, Ayah 42

According to the classical commentators, the miraculous appearance of a healing spring heralded the end of Job's suffering, both physical and mental.

The recuperative process having begun, he was commanded to strike the earth or a rock with his foot, and a fountain or fountains gushed forth,-to give him a bath and clean his body; to refresh his spirits; and to give him drink and rest. This is a fresh touch, not mentioned in S. xxi. or in the Book of Job, but adding beautifully to our realisation of the picture.
