5. Mary: Member of Trinity, Moses' Sister, and Jesus' Mother?
Mary, Sister of Moses
Miriam, Moses' sister, had a father named Amram and brother named Aaron Numbers 26:59. Miriam and Jesus' mother Mary share the same name in Semitic languages: Miryam. But Mary lived 1400 years later.
Yet, the Quran says Mary was born to "the wife of Imran" Quran 3:35-36, is "daughter of Imran" Quran 66:12, and "sister of Aaron" Quran 19:28.
Christians found the "sister of Aaron" problem during Muhammad's lifetime and he responded:
"They used to give names after the names of apostles and pious persons who had gone before them" Sahih Muslim 2135
But he never explains why her father is Imran or why the Quran has a birth narrative of Imran's wife giving birth to Mary. Quran 3:35-37
Mary, Member of the Trinity
The Trinity is Father, Son, and Holy Spirit. But the Quran refutes the Trinity by saying:
"Those who say, 'Allah is one in a Trinity,' have certainly fallen into disbelief ... The Messiah, son of Mary, was no more than a messenger... His mother was a woman of truth. They both ate food" Quran 5:73-75 then has Allah ask Jesus: "Did you ever ask the people to worship you and your mother as gods besides Allah?" Quran 5:116.
Classical Authorities Confirm Christian Trinity = Allah, Mary and Jesus
Ibn 'Abbas (companion of the Prophet)
"This refers to the Trinity: Allah, may He be exalted, and His wife and His son." Ibn Abbas, Tafsir al-Qurtubi

Shaykh al-Islam Ibn Taymiyyah
"With regard to what the Quran says about what the Christians said, 'Allah is the third of the three (in a Trinity)', the commentators said that it refers to Allah, the Messiah and his mother, as Allah." Ibn Taymiyyah, Majmu' al-Fatawa, cited at IslamQA
Ibn Kathir
"Mujahid and several others said that this Ayah was revealed about Christians in particular. As-Suddi and others said that this Ayah was revealed about taking 'Isa and his mother as gods besides Allah, thus making Allah the third in a trinity." Tafsir Ibn Kathir on Quran 5:73
