Did I commit shirk?
Assalamu alaikum, today at my college there was a Puja ceremony (idol worship). I didn’t join in any chants, but they had turmeric, bhasmam, and kumkum for the forehead. I ended up putting it on my forehead. I feel terrible now. Even if I didn’t believe in it at all, I know I shouldn’t have done that. I’m really scared and think I made a big mistake. May Allah forgive me.
