The Mountaineers announced the dismissals Monday night without elaboration.
Ahmad was the team's third-leading scorer this season at 12 points per game and the third-leading rebounder at 5.8. Harris averaged 7.9 points and 4.5 rebounds.
Ahmad is a senior and four-year starter. Harris is a junior in his second year as a starter.
The dismissals come during a tumultuous season for the Mountaineers (10-14, 2-9 Big 12), who are in last place in the league and have lost 10 of their past 12 games.
West Virginia is coming off a 75-53 home loss to Texas and plays at No. 14 Kansas (18-6, 7-4) on Saturday.
