What is the ruling on obtaining money from a competition that does not require paying fees to participate, where the participant is given a free "bonus" (credit/chance) to enter draws?

If the participant does not pay money to enter the competition, then it is not considered Maysir (gambling) or prohibited Qimar (gambling). It is permissible to take its financial prize, provided that the objective of the competition, its means, and its field are lawful.
