AbdelKarim Hasan was the youngest player to appear in the 2011 AFC Champions League at 17 years old, coming off the bench against Esteghlal. His team subsequently emerged champions of the Champions League that year. He was awarded Young Player of the Year in the 2012–13 Qatar Stars League. It was announced in June 2017 that Al Sadd had loaned him to Belgian First Division A side Eupen.

Abdelkarim played in the 2019 FIFA Club World Cup, in which he scored in a 3–1 win over Hienghène Sport. He later scored in the second round 3–2 loss against C.F. Monterrey. Al-Sadd eventually finished in the 5th place.

International career

Abdelkarim scored a goal against UAE U20 in the 10th International Friendship Youth Tournament.

In a friendly match against the Malaysia U-23 side on 17 June 2012, Abdelkarim sparked a mass melee between the two sides after a two-footed lunge on Mohd Azrif in the 43rd minute. He was duly shown a red card for his challenge. Afterwards, a Malaysian player, Nazmi Faiz, ran half the length of the pitch to confront him, and punched him. Being 5 inches shorter than Abdelkarim, Nazmi's punch turned into nothing more than a push on his chest. Nazmi Faiz was shown a red card, whereas Qatar went on to lose 2–0.

He scored a goal in Qatar's opening game against Maldives in the qualifying stage for the 2014 AFC U-22 Asian Cup.

Abdelkarim made his debut for the senior national team on 18 November 2010 against Haiti.

He was the youngest player to appear in the preliminary squad list for the 2011 Asian Cup at the age of 17 years and 123 days old. He scored Qatar's only goal against Malaysia in the 2015 AFC Asian Cup qualifiers to ensure Qatar a berth in the Asian Cup. He also scored a goal in Qatar's 4–1 victory against Yemen in the qualifiers.

Though his team lost all their group stage games in the 2015 AFC Asian Cup, he was extolled as one of the stars of the tournament. A FIFA.com featured article theorized that he would form the basis of young players who go on to represent Qatar at the 2022 FIFA World Cup.
