Is it permissible to bet on light arms shooting among five people, with each paying 100 riyals, and the winner taking the total of 500 riyals with encouragement? And does this fall under the Hadith: "There is no wagering except in three," and what Ibn al-Qayyim mentioned in the chapter on horsemanship?

If the contestants pay the prize money themselves, it is considered gambling and prohibited according to the majority of jurists, unless they introduce an arbitrator (muhallil) among them. However, Ibn al-Qayyim held the view that betting is permissible without an arbitrator, which is closer to the objectives of Islamic law, as the hadith stipulating the condition of an arbitrator has not been definitively established. Although this opinion is strong, the opinion of the majority is more cautious. The questioner should include an arbitrator in their bet as a precaution and to avoid disagreement. Betting with modern weapons is permissible as they fall under the meaning of a blade and what is useful in war.
