'' The Prophet used to wake up with the rooster crowing and then praised Allah, affirmed His Greatness and Oneness, pleaded with Him, and then brushed his teeth with the miswak. He then performed ablution and stood before his Lord and recited His Words (the Qur'an), praising Him and placing his hope on him with eagerness and fear. What actions can be better in preserving the health of the heart, body, soul, strength in general and that bring favors to this life and the next than these? ''
