Jacob's Wives - from the People of the Book
The People of the Book also said that when Jacob came to his maternal uncle in the land of Haran, his uncle had two daughters. The elder one was called Leah (Lia) and the younger one was Rachel (Rahil). The latter was the better and lovelier of the two. His uncle agreed to marry his daughter to him on the condition that Jacob pasture his sheep for seven years.
After a period of time, his uncle prepared a feast and gathered people for the wedding. He married Leah, his elder daughter, to him at night. She was weak-sighted and ugly. When morning came, Jacob discovered that she was Leah and he complained to his uncle: 'You deceived me; I was engaged to Rachel and you married me to Leah." His uncle said: "It is not our tradition to marry the younger daughter before the elder daughter. However, if you love her sister, work another seven years and I will marry you to both of them."
Jacob worked for seven years and then married Rachel. It was acceptable in their time, as described in the Torah, for a man to marry two sisters. Laban gave a female slave to each daughter. Leah's slave was called Zilpah and Rachel's slave was called Bilha.


Jacob's Children - from the People of the Book
Almighty Allah compensated Leah's weakness by giving her sons. The first one was named Reuben (Robel), after whom there were Simeon (Shamun), Levi (Lawi), and Judah (Yahudh). Rachel felt jealous of Leah's having sons, as she was barren. She gave her slave Bilha to her husband and he had relations with her until she became pregnant. She gave birth to a son and named him Naphtali.
Leah was vexed that Rachel's slave had given birth to a son, so she, in turn, gave her slave Zilpah to Jacob . Zilpah gave birth to two sons, Gad and Asher. Then Leah got pregnant and gave birth to her fifth son, Isssachar, and later she gave birth to a sixth son, Zebulun. After this Leah gave birth to a daughter named Dinah. Thus, Leah had seven children from Jacob.
Then Rachel prayed to Allah to give her a son from Jacob. Allah heard her call and responded to her prayer. She gave birth to a son, great, honorable, and beautiful. She named him Joseph (Yusuf).
All of this happened when they were in the land of Haran and Jacob was pasturing his uncle's sheep, which he did for a period of twenty years.
