March 2

We, verily, have set forth all things in Our Book, as a token of grace unto those who have believed in God, the Almighty, the Protector, the Self-Subsisting. And We have ordained obligatory prayer and fasting so that all may by these means draw nigh unto God, the Most Powerful, the Well-Beloved. We have written down these two laws and expounded every irrevocable decree. We have forbidden men from following whatsoever might cause them to stray from the Truth, and have commanded them to observe that which will draw them nearer unto Him Who is the Almighty, the All-Loving. Say: Observe ye the commandments of God for love of His beauty, and be not of those who follow in the ways of the abject and foolish.
