In March 2007, he and Mohammad Sami were called up as replacements in Pakistan's squad for the 2007 Cricket World Cup after Shoaib Akhtar and Mohammad Asif were ruled out through injury.
On 8 December 2007, Arafat made his Test match debut for Pakistan against India in Bangalore in the third and final Test of the series. He displayed his all-round abilities by taking 7 wickets in the match including a 5-wicket haul, and scoring a useful 44 in the first innings.
It has been reported (2nd August, 2008, Hindustan Times, Karachi) that he has signed with the Kolkata Knight Riders to play in the second season of the Indian Premier League 20/20 tournament in 2009.
The Kent fans seem to have immediately taken to Arafat. At their recent Friends Provident Trophy game against Surrey at The Brit Oval they often chanted of 'There's only one Yasir Arafat', later on, as a pun, 'There's only two Yasir Arafat's'. Others included 'We've nicked your tea towel', also in jest.
In 2004, Arafat performed the extremely rare feat of taking five wickets in six balls for Rawalpindi against the national champions Faisalabad in the Quaid-e-Azam Trophy. This had only been achieved three times previously in the entire history of first-class cricket, by Bill Copson in 1937, William Henderson in 1938, and Pat Pocock in 1972. Arafat was the only bowler to take the wickets spread over two innings.
Arafat is an old fashioned seam bowler and is able to swing the ball both to and from the batsman.
