The year is like a tree, months are its branches, days are the branch sticks, hours are its leaves, and the breaths are its fruits. Therefore, if one’s breaths are in obedience [to Allah and His Messenger], the fruits of his tree are good. If they are in disobedience, his fruits are bitter… The harvest is on the Appointed Day, when one’s fruits are found out to be either good or bitter. — Ibn al-Qayyim
