Is participation, profit, and loss in the competition on the "Alukah" website halal or haram?

There is no objection to participating in the aforementioned competition and adhering to its conditions, as long as it does not involve anything prohibited by Islamic law, because its subject matter consists of beneficial scientific issues. It is permissible to receive prizes for competitions if they are in accordance with what the Messenger of Allah, peace and blessings be upon him, specified, or if they are in religious scholarly matters, provided that the prize is permissible.
