[5] In March 2006, Hassan played a match for Afghanistan against a Marylebone Cricket Club team led by Mike Gatting in Mumbai.

Afghanistan then had 12 overs to bowl to Canada before the end of the day, and Hassan managed to take four wickets for 12 runs before stumps.

Hassan then took three early wickets in Canada's second innings to record his third ten-wicket haul, and he was named the player-of-the match in a nine-wicket win.

[52][53][54] Hassan was selected to play for a combined Associate and Affiliate XI in a tour match against England in Dubai in January 2012.

Hassan took two early wickets in England's first innings, but on the second day he fell over the boundary fence and injured himself, causing him to miss the rest of the match.
