“Remembrance of God is like the rain and dew…”

Remembrance of God is like the rain and dew which bestow freshness and grace on flowers and hyacinths, revive them and cause them to acquire fragrance, redolence and renewed charm. "And thou hast seen the earth dried up and barren: but when We send down the rain upon it, it stirreth and swelleth, and groweth every kind of luxuriant herb." [Qur'án 107:5] Strive thou, then, to praise and glorify God by night and by day, that thou mayest attain infinite freshness and beauty.
