Ibn Ishaaq stated that he was a man of Rum. His names was Job Ibn Mose Ibn Razeh Ibn Esau Ibn Isaac Ibn Abraham. Someone else said he was Job Ibn Mose, Ibn Rimil Ibn Esau Ibn Isaac Ibn Jacob. There have also been other statements in his lineage. Ibn Asaker narrated that his mother was a daughter of Prophet Lot.It was said, also, that his father was one who believed in Abraham when he was cast into the fire.
The first opinion is the most plausible as he was a descendant of Abraham's offspring as Allah Almighty declared:
"That was the reasoning about Us which We gave to Abraham (to use) against his people: We raise whom We will degree after degree: for thy Lord is full of wisdom and knowledge. We gave him Isaac and Jacob: all (three) We guided: and before him We guided Noah and before him We guided Noah and among his progeny David Solomon Job Joseph Moses and Aaron: thus do We reward those who do good" Quran 6:83-84
Allah the Almighty praised His worshipper Job in His Glorious Quran:
"Truly! We found him patient. How excellent a slave! Verily, he was ever oft-returning in repentance to Us" Quran 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 displease, 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 excellent patience and always remembers his Generous Lord. He is an excellent model for the worshippers 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."
Iblis, overhearing all this, became annoyed. He planned to tempt Job to corruption and disbelief, so he hastened to him. He tried to distract Job from his prayers by whispering to him about the good things in life, but Job was a true believer and would not let evil thoughts tempt him. This disturbed Iblis more; thus he began to hate Job even more.
