Every day the sun rises it calls upon us, O people! I am a new day; I am an observer of your actions. Take advantage of me for I will not return until the Day of Judgment. O son of Adam, you are nothing but a few breaths. Once one breath goes out, part of you goes with it. In the same way that part of you has gone, soon all of you will go.
