Aslam o Alakom to whom ever is reading this, So some further context: My school hands out cards to people who do good deeds or portray good character traits. You can redeem cards by putting it in a raffel, at the end of the week whoever wins the rafel wins a gift card or candy. Is it haram for me to participate in this?
Wa 3laykum As Salaam,
I hope you are doing well. With regards to just cards there is nothing inherently wrong with as they are not religious nor pertain to any non-Islamic belief.
And as long as you dont use money to purchase the raffle then it should be permissible.
ALLAH (Glory Be To HIM) Knows Best
