Aslam Khan Malik was born on November 1, 2001, in Malaysia. Raised alongside his brothers Amir Khan Malik and Rahim Khan Malik, he developed his game through the local domestic setup before advancing into regional representative teams. A explosive right-handed batter who also offers secondary utility as a wicketkeeper, he established himself as a dynamic middle-order finisher capable of accelerating scoring rates in the death overs.

He made his T20I debut for Malaysia on December 22, 2022, against Singapore at the Bayuemas Oval in Klang. Adapting quickly to the international arena, he carved out a role as a middle-order hitter whose aggressive intent gave Malaysia late-innings momentum. His career-highlight performance came during a high-scoring T20I encounter where he struck a fluent 77 vs Singapore in the Asia Pacific Champions Trophy 2025, demonstrating his capability to single-handedly clear boundaries under pressure.

Across 2025 and 2026, Aslam became a regular feature in Malaysia's white-ball campaigns. He featured prominently in domestic franchise tournaments for Northern Strikers and represented the national team during the 2025 ICC Men's T20 World Cup Asia-EAP qualifiers, the 2026 series against Bahrain and Indonesia, and the 2026 Asian Games Men's T20I Qualifier in Singapore.

By September 2026, following the bilateral home series against the United Arab Emirates, Aslam Khan Malik alongside his brothers Amir and Rahim remained central figures in Malaysia's middle-order composition. He was then picked in the Malaysian squad for the 2026 Asian Games as well.
