Keren-happuch was a daughter of the prophet Job. After Job repented, God blessed Job with seven sons and three daughters, including Keren-happuch. The Book of Job describes Keren-happuch and her sisters as being the fairest daughters in all the land. Job granted his daughters a share of his inheritance.
So We answered him [Job], and removed the affliction that was upon him, and We gave his people, and the like of them with them, mercy from Us, and a Reminder to those who serve.— Surah 21:84 (Arberry)
And We gave to him [Job] his family, and the like of them with them, as a mercy from us, and a reminder unto men possessed of minds.— Surah 38:43 (Arberry)
He [Job] had seven sons and three daughters. And he called the name of the first [daughter] Jemimah, and the name of the second Keziah, and the name of the third Keren-happuch. In all the land there were found no women so fair as the daughters of Job; and their father gave them an inheritance among their brothers. After this, Job lived 140 years, and saw his sons and his grandsons, four generations. So Job died, an old man and full of days.— Job 42:13–42:17 (AMP)
