Aleem is best known as an international cricket umpire. He made his international umpiring debut in an ODI between Pakistan and Sri Lanka at Gujranwala on 16 February 2000. In 2002 he became a member of ICC's International Panel of umpires. He was chosen to umpire at the ICC Cricket World Cup. In April 2004, he became the first Pakistani to be part of the Elite Panel of ICC Umpires. He was nominated for the ICC Umpire of the year Award in 2005 and 2006, beaten on both occasions by the Australian Simon Taufel. On 17 October 2007 Aleem umpired in his 100th ODI, making him the tenth umpire in the history of cricket to reach that landmark. He reached the landmark in a record time, taking just seven years, and became the first Pakistani to officiate in a century of One Day Internationals. Aleem has stood in a solitary India-Pakistan ODI match at Karachi 2006 and five Ashes Test matches. He was also one of the on-field umpires for the final of the 2006 ICC Champions Trophy, standing alongside Rudi Koertzen. He was appointed to stand in the final of the 2007 Cricket World Cup between Australia and Sri Lanka, where he officiated with Steve Bucknor. Dar was also selected to stand in the final of the 2010 ICC World Twenty20 between Australia and England. In January 2005, Aleem and his colleague Steve Bucknor, received death threats during a Test match between England and South Africa at Centurion. He was also involved in a controversy during the 2007 Cricket World Cup final where he, along with fellow officials Bucknor, Koertzen, Bowden and Crowe incorrectly made Australia bowl three unnecessary overs in near darkness. Consequently, the ICC decided to suspend him, along with the other four officials, from duty for the next ICC event, which was the 2007 World Twenty20 Championship. Aleem proved his accuracy at the 2011 Cricket World Cup when all the 15 Umpire Decision Review System appeals against him were struck down. He was selected as one of the twenty umpires to stand in matches during the 2015 Cricket World Cup. In April 2019, he was named as one of the sixteen umpires to stand in matches during the 2019 Cricket World Cup. The following month, in the second match of the 2019 Ireland Tri-Nation Series, he became the third umpire, and first from Pakistan, to officiate in 200 ODIs.
Accolades
After being nominated twice in 2005 and 2006, Aleem finally won the Umpire of the Year award in October 2009, at the annual ICC awards ceremony in Johannesburg, South Africa. By claiming the award, Aleem ended Simon Taufel's run of five successive awards. It was the first time that any umpire other than Taufel had picked up the accolade in the six years that the ceremony has taken place. In October 2010, he won the award for a second straight year. In September 2011, he was named best umpire for the third consecutive year. On 14 August 2010, the Government of Pakistan honoured him with the President's Award for Pride of Performance. He was honoured by ICC for officiating in 150 ODIs.
