Assalamu alaikum, im mot sure if i committed shirk or not and i couldnt find the answer to my question anywhere.Today i was looking at someones profile on social media and i really liked their takes on topics so i made this sign 🤞🏼 to symbolize were locked in together as a joke and this sign is also used by christians to symbolize “jesus Protection” (astaghfirullah) so did i commit shirk? i don’t know what to do.
