What was the reason behind the no refueling decision in F1

Was this decision made to save money in the racing calendar or was this done to prevent the controversy that happened a few times this year that one car was released by the lollypop man after fuel was taken onboard by one racer and another team fuelled with less fuel to try and jump a competitor in the middle stint? This is a bone of contention that can only be explained by the powers residing over the management of Formula1. The question at the top of my mind is : How will qualifying be influenced by this rule, will the team have to qualify with a full fuel tank and then have a certain amount of fuel added at the end of qualifying or will the team qualify with a empty fuel tank and then be allowed to add any amount of fuel at the end of the qualifying.

By my reasoning both ways of implementation will have benefits and disadvantages to next years racing. The benefit of the qualifying and addition of a certain amount of fuel will be quite heavy on the tyre usage but the team with the best car with a full tank will benefit. The advantage of the second type of qualifying will be that the fastest car will be at the front of the grid but the race might get compromised with filling the car and you might get a long procession of F1 cars that can’t overtake the front car until it is lighter.

I will be searching for answers and you are welcome to air your concerns and thinking around this factor in next years F1
