Surah 39:8
"When hardship touches a person, he calls on his Lord, turning to Him (in repentance). Then, when He bestows blessing on him from Himself, he forgets what he was calling to Him for before, and sets up rivals to God to lead (people) astray from His way. Say: ‘Enjoy (life) in your disbelief for a little. Surely you will be one of the companions of the Fire.’"
– When hardship touches a person, he calls on his Lord
This extended passage (vv. 8–22) compares Allah’s faithful servants with those who set up rivals to Allah. The passage includes a series of “say” statements in which the messenger testifies about himself and challenges his audience (vv. 11–16). The losers are punished and the believers rewarded on the Day of Resurrection.
