The story
Ayyub had everything a man can lose: wealth, lands, children, health. Then he lost it, layer by layer, until illness sat on him for years and only his wife's loyalty remained. The whisperer waited for the complaint that never came. When Ayyub finally turned to his Lord, listen to the manners in it: 'Adversity has touched me, and You are the Most Merciful of the merciful' (21:83). No accusation, no demand, barely even a request; a description laid at the door of Mercy.
The answer restored him with interest: 'Strike the ground with your foot; here is a cool washing and a drink' (38:42). Healing rose from under his own heel, family was returned and doubled, 'a mercy from Us and a reminder for those of understanding' (38:43). Even his tender dilemma, an oath sworn in illness to discipline his wife, was solved by heaven with gentleness: take a bundle of grass and fulfill the oath's letter without its harshness (38:44).
The Qur'an closes his file with the words every sufferer hopes to earn: 'Indeed We found him patient. An excellent servant! He was ever turning back' (38:44).
