Definitely not.
Khabib has a history of cheating. One of the most glaring examples is his last fight before joining the UFC. His opponent was a regional journeyman with 20+ losses and Khabib still felt the need to cheat by grabbing the ropes to prevent a takedown. Khabib's cheating was so egregious that the referee finally took a point away.
Here is another example. Khabib cheated by shamelessly grabbing Tibau's shorts to try to stop takedowns. Even with Khabib cheating, Tibau was still able to take him down.
Khabib also cheated repeatedly on the scale. He missed weight against Trujillo. He no-showed the weigh-ins with the interim belt on the line at UFC 209 against Tony Ferguson because he was overweight. Khabib eventually would only fight in Abu Dhabi without an athletic commission, so he could do sham weigh-ins.
