This is not the first time that Mr Marzey has been injured in a terror strike. In 2007, when he was 18, he was hurt in the leg in the blast at Hyderabad's Mecca masjid, which killed 17 people.
A shaken Mirza Shahid, Abdul Wasey's father, says, "I am hopeful my son will fight this too and come out of hospital. The culprits should be brought to book."
Mr Marzey is one of 117 people injured in yesterday's blasts. Many were, like him, young people in their early 20s.
Sixteen people died in Thursday's blasts, among them two MBA students and a 24-year-old man who wanted to be a policeman.
