(V.10:19) Narrated Abu Hurairah رضي الله عنه: The Prophet صلى الله عليه وسلم said, "Every child is born on Al-Fitrah [true faith of Islâmic Monotheism (i.e. to worship none but Allâh Alone)], but his parents convert him to Judaism or Christianity or Magianism, as an animal gives birth to a perfect baby animal. Do you find it mutilated?" (Sahih Al-Bukhari, Vol.2, Hadith No.467). [See also the Qur’ân, Verse 30:30]
