It also says that Judah, the son of the Prophet Jacob, married his eldest son to a woman named Tamar. The son used to approach her from behind, so Allah became angered by his act and caused him to die. Judah then married his next son to her; whenever that son went in to her he spilled his semen on the ground, knowing that if she conceived the first child would be called after—and counted as—the child of his deceased brother.

He slept with her, and she conceived by him. From that very child descended the Prophet David (4).
Thus they have depicted him as the offspring of adultery—just as they have claimed that the Messiah was born of adultery—and they were not content with that until they attributed it to the Torah itself.
