BAPTISM
The only allusion to Baptism in the Qur’an is found in Surah ii. 132: “(We have)the baptism of God, and who is better to baptise than God?” The word here translated baptism is sibghah, lit. “dye,” which, the commentators al-Jalalain and al-Baizawi say, may, by comparison, refer to Christian baptism, “for” says al-Baizawi “the Nasra (Christians) were in the habit of dipping their offspring in a yellow water which they called al-Ma’mudiyah and said it purified and confirmed them as Christians” (See Tafsiru ‘l-Jalalain and Tafsiru ‘l-Baizawi in loco.)
