When I was a child, me, and my friend were playing, when I took something from him for fun. Then he started begging me to give it. Then, I don't know why, but I told him to prostrate to me if he wanted it. I guess I was copying what people do on television. Then he did it, and I gave it back.
It was only recently that I realized how serious it is to prostrate to anyone other than Allah. As a child I didn't know how serious it was, but my cousin pointed it out.
Would Allah (SAW) forgive me for not knowing, and after asking forgiveness of Allah (SAW), should I ask forgiveness from my friend (even though we were both joking and he knew I was going to give it back)?
