Qur'an 20110219

In the name of Allah, most Gracious, most Merciful.

189. They ask you concerning the New Moons. Say, "They are but signs to mark fixed periods of time in men, and for Pilgrimage." It is no virtue if you enter your houses from the back: it is virtue if you fear Allah. Enter houses through the proper doors, and fear Allah, that you may prosper.

They are but signs to mark fixed periods of time in men, and for Pilgrimage.

The Islamic calendar is a lunar calender. The new moons are used to measure time, and that's it. There are no superstitions involved, and there is no worship of the moon.
