Lady Maryam

Prophets

My grandmother, who is a religious Greek orthodox Christian, has claimed to have seen the Virgin Mary. Is it possible in Islam for someone to see her in a vision? Sayyed Mohammad Al-Musawi	I understand that the father of Mary in the Bible is Joachim but in the Quran the father of Maryam is Imran and she is also called by her nation as the sister of Harun. How does one reconcile these differences? Sayyed Mohammad Al-Musawi
Why does Allah say he can not have a son without a consort but in another verse He says that Maryam (a) had a son without partner? Sayyed Muhammad Husaini Ragheb
