Muhsin ibn Ali

Muhsin ibn Ali (Arabic: المُحَسِّن بْنُ عَلِيّ), also spelled Mohsin, was the youngest son of Fatima bint Muhammad and Ali ibn Abi Talib, and thus a maternal grandson of the Islamic prophet Muhammad. He was a brother of Husayn and Hasan. Controversy surrounds the fate of Muhsin as some canonical Shia sources report that Muhsin died in miscarriage, following a raid on Fatima's house led by Umar, a companion of Muhammad. Alternatively, Sunnis hold that Muhsin died in infancy of natural causes.
