Ball's opposite rotation caused by friction

ThinkAssume that you push a ball like in the picture (thealong the red line) with your hand with a greatsome force.enter image description here

The ball will go awaymove forward while its rotating in this way: enter image description here

And after some movingmovement, the ball will stop movingtranslating(still rotating) and it again moves towardback towards you. How does friction work here? How is this motion possible?
