Stars

Though not used during worship, incense is used throughout the Islamic world to remind the believers of the rewards of righteous believers in Paradise:

The first group of people, who will enter Paradise, will be glittering like the full moon and those who will follow them, will glitter like the most brilliant star in the sky.
