Abdel-Aziz recognized Khabib's contribution to the sport

"Six years ago this young lion from the small village of Sildi changed the future of sport and opened doors for many young boys and he made us proud to be Muslims and he left us with many winged phrases. It was an honor to be with him all this time," Abdel-Aziz wrote.

Earlier, Abdel-Aziz called complete nonsense rumors that Khabib could perform at the UFC 300th anniversary tournament, which will be held on the night of April 13-14 in Las Vegas.
