Obligatory Prayer & Fasting

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.
