The details of Lalon's early life are controversial and impossible to verify. Lalon also recorded very little information about himself, as he considered his spiritual endeavors to be a private matter. As a result, accounts of Lalon's life are often contradictory and unverifiable. However, a general backstory of Lalon's early life exists in the popular culture.
Around the age of sixteen he was found floating by the bank of Kaliganga river, suffering from smallpox. He was taken to the home of Maulana Malam Shah and his wife Matijan, who brought him up. Lalon was in a near comatose state for many months and when he recovered lapsed into complete amnesia from which he never recovered in life.
Though Lalon's origins are unclear, it is believed that he had no formal education and lived in extreme poverty
