What is the ruling on obtaining prizes from a cultural competition by submitting multiple answers under different names, knowing that there is nothing in the competition's terms and conditions that prevents this?

There is no impediment to participating in permissible cultural competitions and receiving their prizes if they are offered by a donor to encourage contestants to learn. However, if participation requires payment of a sum or purchase of a coupon, it becomes gambling. Participants must adhere to the competition's terms and conditions, and any violation thereof is considered prohibited deception. Submitting multiple entries under different names to obtain multiple prizes is wrong and requires repentance and returning what was acquired through it, as this contradicts justice and the purpose of the competition.
