Allah the Almighty praised His worshiper Job in His Glorious Qur'an: Truly! We found him patient. How excellent (a) slave! Verily, he was ever oft-returning in repentance (to Us)! Surah 38: 44
Job was repentant, remembering Allah with thankfulness, patience, and steadfastness. This was the cause of his rescue and the secret of Allah's praising him.
A group of angels were discussing Allah's other human creatures, how those who were humble earned Allah's pleasure, while those who were arrogant incurred His displeasure. One of the angels remarked: 'The best creature on earth today is Job, a man of noble character who displays great patience and always remembers his Generous Lord. He is an excellent model for the worshipers of Allah. In return, his Lord has blessed him with a long life and plenty of riches, yet he is never haughty or selfish. His family, his servants, as well as the needy and the poor share in his good fortune; he feeds and clothes the poor and buys slaves to set them free. He makes those who receive his charity feel as if they are favoring him, so kind and gentle is he."
