Ameer al-Momineen (a.s) said: “One who makes no progress from one day to the next is at a loss. Whoever struggles in this life for the material goods of this world will feel sorry when he dies and has to leave them behind. Whoever gets worse day by day is deprived. Whoever does not worry about what he has saved for the Hereafter is ruined even if he has a good life. Whoever does not worry about his spiritual weaknesses will be overwhelmed by his selfish desires. Death is better for anyone who faces spiritual collapse. The life of this world is nice and sweet and there are many who love it. There are also some people who love the life of the Hereafter and have separated their way from those who are haughty and in love with this world. They do not compete with others in this world. They will not get pleasure from its blessings and from life, and will not get sad about the hardships in life. Whoever fears an enemy attack will stay up late at night. How fast do your days and nights pass-by! Watch your tongue and be careful about your words. Say less but say good things. Prefer for others what you prefer for yourself. Treat others the way you like them to treat you.” Then he faced the companions and said
“O' people! Look at the people and see how they live, each with a different situation, passing their days until the night. One is fallen down and is trying to get up. Another one is ill. That other one is about to die, and has no more hopes. The other one has died and is in the coffin about to be buried. One is seeking this world while death is seeking him. One is ignorant while he has not been ignored. Those who remain pursue what those who died before pursued. God created some people who are not attracted to this world. He made them abstinent regarding worldly goods. They got attracted to the secure house to which God called them. They were patient, and put up with the hardships in life, and were eager to attain the nobility that is near God. They gave their life to please God, and their deeds ended with martyrdom. They visited God while God was pleased with them. They realized that death is inevitable for those who lived in the past and those who will live in the future. Therefore they saved up things different from gold and silver for the Hereafter. They put on rugged clothes, and ate little, and preferred nobility. They became friends for God's sake or became enemies for the sake of God. These people are guiding lights in this world, and will be surrounded by blessings in the Hereafter. Peace be upon you!”
