Islam & Christianity are two important African religions. (:
I'd have to say Christianity for certain and with the rise of Islam, then Islam is number two.
No date is known because there is no real schism in Islam. There is no schism in Islam in the sense as known in Christianity. In Christianity, there are many denominations and different churches and different ritual worships. However, in Islam, differences between the two main Islamic groups, Shiites and Sunnis, are within minor details and minor differences in interpretations of Quran and Prophet Muhammad Sunnah (sayings and practices). Refer to question below for more information.

Some recommended Christian books about Islam that provide insight into the relationship between the two faiths include "A Common Word: Muslims and Christians on Loving God and Neighbor" by Miroslav Volf and "The Cross and the Crescent: Understanding the Muslim Heart and Mind" by Phil Parshall. These books offer valuable perspectives on the similarities and differences between Christianity and Islam, fostering understanding and dialogue between the two faiths.
