A charitable association wishes to run a donation campaign for educating orphaned students. The proposed plan is as follows: Firstly, a contract is made with a website specialized in selling tickets online. Secondly, donations are collected through the sale of tickets on this specialized company's website, offered at specific price tiers. The proceeds from the ticket sales are steered towards educating the orphans, after deducting a specified percentage of the ticket's value as a commission for the website. Thirdly, one point is calculated for every dinar spent by individuals who purchase tickets. Fourthly, a draw is conducted from the names of those who purchased tickets for the purpose of distributing material prizes, such as phones, smart watches, tablets, etc. It is noted that these prizes are provided by sponsoring companies (a third party) and will not be purchased by the fund using the money from the tickets sold, which is intended for distribution to the winners. What is the ruling of Islamic Law on this?
