My cheeky friend turn-on the DND mode on my iPhone and I am a little retard in navigation on phone. Please help me to turn it off.

To quickly turn off Do Not Disturb on your iPhone, swipe down from the top-right corner of the screen (or up from the bottom on older models) to open Control Center, then tap the crescent moon icon. When it’s no longer highlighted, Do Not Disturb is off.
