Irfan Hafiz, a Sri Lankan author known as "Keyboard Warrior", has passed away at the age of 37.

Diagnosed with a rare disease called Duchenne Muscular Dystrophy since the age of 4, Irfan Hafiz spent most of his life in bed.

While battling his illness, he authored three books and was considered an inspirational character by many.

"I could study only up to grade 05. I was confined to a wheelchair at the age of 12 and I've been confined to bed since I was 18," Hafiz said, in one of his memoirs. 

Nas Daily, one of the most successful content creators on Facebook, described Irfan as the "most inspiring man ever".
