Quranic verses confirm the virgin birth of Jesus. Sura Maryam; Verses 16 to 35.
It is worth mentioning that Prophet Jesus (Easa)(AS) is mentioned in Quran 25 times exactly like the number of the mention of Prophet Adam (AS) who is also mentioned in Quran 25 times. Allah (The Most Glorious) says in Quran ( Verily, the likeness of Jesus with Allah is the likeness of Adam, Allah created him from clay then told him be, and he was). Adam was created with out parents and Easa was created with out father. Both are miraculous.
