The Quran confuses Mary, the mother of Jesus, with Miriam the sister of Moses. The Quran identifies Mary as the sister of Aaron, the daughter of Imran, whose mother was the wife of Imran:
When the wife of Imran said, 'Lord, I have vowed to Thee, in dedication, what is within my womb. Receive Thou this from me; Thou hearest, and knowest.' And when she gave birth to her she said, 'Lord, I have given birth to her, a female.' (And G-d knew very well what she had given birth to; the male is not as the female.) 'And I have named her Mary, and commend her to Thee with her seed, to protect them from the accursed Satan.' S. 3:35-36 Arberry
Then she brought the child to her folk carrying him; and they said, 'Mary, thou hast surely committed a monstrous thing! Sister of Aaron, thy father was not a wicked man, nor was thy mother a woman unchaste.' S. 19:27-28
And Mary, Imran's daughter, who guarded her virginity, so We breathed into her of Our Spirit, and she confirmed the Words of her Lord and His Books, and became one of the obedient. S. 66:12
Compare this to what the Holy Bible says:
"Then Mary (Hebrew- Mariam), the prophetess, the sister of Aaron, took the timbrel in her hand…" Exodus 15:20
"The name of Amram's wife was Jochebed, the daughter of Levi, who was born to Levi in Egypt; and to Amram she bore Aaron and Moses and their sister Miriam." Numbers 27:59
"The children of Amram: Aaron, Moses, and Miriam. The sons of Aaron: Nadab, Abihu, Eleazar, and Ithamar." 1 Chronicles 6:3
"For I brought you up from the land of Egypt and redeemed you from the house of slavery, and I sent before you Moses, Aaron, and Miriam." Micah 6:4
"Miriam and Aaron spoke against Moses because of the Cushite woman whom he had married, for he had married a Cushite woman. And they said, ‘Has the LORD indeed spoken only through Moses? Has he not spoken through us also?" And the LORD heard it. Now the man Moses was very meek, more than all people who were on the face of the earth. And suddenly the LORD said to Moses and to Aaron and Miriam, ‘Come out, you three, to the tent of meeting.’ And the three of them came out. And the LORD came down in a pillar of cloud and stood at the entrance of the tent and called Aaron and Miriam, and they both came forward… When the cloud removed from over the tent, behold, Miriam was leprous, like snow. And Aaron turned toward Miriam, and behold, she was leprous. And Aaron said to Moses, ‘Oh, my lord, do not punish us because we have done foolishly and have sinned. Let her not be as one dead, whose flesh is half eaten away when he comes out of his mother's womb.’ And Moses cried to the LORD, ‘O G-d, please heal her--please.’ But the LORD said to Moses, ‘If her father had but spit in her face, should she not be shamed seven days? Let her be shut outside the camp seven days, and after that she may be brought in again." So Miriam was shut outside the camp seven days, and the people did not set out on the march till Miriam was brought in again." Numbers 12:1-5, 10-15
