Thus, since each of these five times points to a mighty revolution, is a sign indicating the tremendous dominical activity, and a token of the universal Divine bounties, it is perfect wisdom that being a debt and an obligation, the prescribed prayers should be specified at those times.
Glory be unto You! We have no knowledge save that which You have taught us; indeed You are All-Knowing, All-Wise.5
O God! Grant blessings and peace to the one whom You sent as a teacher to Your servants to instruct them in knowledge of You and worship of You, and to make known the treasures of Your Names, and to translate the signs of the book of the universe and as a mirror to its worship of the beauty of Your dominicality, and to all his Family and Companions, and have mercy on us and on all believing men and women. Amen. Through Your Mercy, O Most Merciful of the Merciful!
