Afghanistan has the highest number of immigrants in the world. There are 4-5 million Afghan immigrants worldwide, of which 3 million live in Iran. One of them, Mohammad Sheyda, was born in Bamiyan in 1984, Afghanistan. When Mohammad was 3 years old, he immigrated to Iran with his family. He lived in Iran for 11 years and then returned to Afghanistan in 1994.

He has been interested in sports since childhood. He started Kung Fu at the age of 15. When he was 18, he lost his right leg. His father was also killed by Taliban in the same year. The long war and the continuing upsurge in violence forced Mohammad and his family to immigrate to Iran again. This time he started cycling and disabled-football training. Mohammad lived with his family in Shiraz. He had to work hard to make a living. He gained fourth place in cycling at the 2010 Asian Olympic Games in China. Afterwards, he decided to do his best to participate in the London 2012 Olympic Games. He had a dream of London and to realise his dream he trained 8 hours a day, every day. However, his dream didn't come true. Maybe the bad economic conditions, the plight of Afghan refugees and the discriminatory government of Iran had made him give up his dream.
