Then I was guided is a book written by the Tunisian Muslim scholar Mohammed Al-Tijani.
Mohammed Al-Tijani converted into Shia Islam after ongoing research. He eventually rejected the Sunni and Wahabi account of history and beliefs and became a Shia. He found the Shia belief and arguments for their account of history to be valid and sourced, and he began to write about it. "Then I was guided" is his first book in a series of future books which he later on went on to write. Later on hundreds of other Sunnis and Wahabis converted into Shiasm after reading his book.
