In Yusuf and his brothers, that is in their story and their discourse, there are signs and indications of Allah's power and wisdom in everything for those who ask about their story and know it. It is said that there are signs of the prophethood of Muhammad, blessings and peace be upon him, for those who asked him about it from the Jews, so he informed them of the truth without hearing from anyone or reading a book.

And it was read as 'sign' and in some copies of the Qur'an as 'lesson.' It is said that Allah, glorified and exalted is He, narrated to the Prophet, blessings and peace be upon him, the story of Yusuf and the wrongdoing of his brothers against him, because he saw the wrongdoing of his people against him so that he may take him as an example. It is said their names are:

Judah, and Reuben, and Simeon, and Levi, and Naphtali, and Issachar, and Dan, and Gad, and Asher:

The first seven were from Leah, the daughter of Jacob's aunt, and the last four were from two maidservants: Zilpah and Bilhah. When Leah passed away, he married her sister Rachel, and she bore him Benjamin and Yusuf.
