Cling firmly to obligatory prayer and fasting. Verily, the
religion of God is like unto heaven; fasting is its sun, and obligatory prayer
is its moon. In truth, they are the pillars of religion whereby the righteous
are distinguished from those who transgress His commandments. We entreat God,
exalted and glorified be He, that He may graciously enable all to observe that
which He hath revealed in His Ancient Book.

Fasting', prepared by the Research Department of the Universal House of Justice)
