131. Amīr al-mu’minīn, peace be upon him, heard a man abusing the world and said: O you who abuse the world, O you who have been deceived by its deceit and cheated by its wrongs. Do you covet the world and then abuse it? Do you accuse it or it should accuse you? When did it bewilder you or deceive you whether by the decay and fall of your forefathers, or by the sleeping places of your mothers under the ground? How much you looked after them in their illness and nursed them during sickness, desiring them to be cured and consulting physicians for them in the morning when your medicine did not avail them and your wailing for them did not benefit them. Your mourning over them did not prove useful to them and you could not achieve your aims. You could not ward off (death) from them with all your power. In fact, through the dying man the world presented an illustration for you and showed you by the example of his falling down how you would (also) fall.
Certainly, this world is a house of truth for him who appreciates it; a place of safety for him who understands it; a house of riches for him who collects provision from it (for the next world); and a house of instructions for him who draws instruction from it. It is the place of worship for the lovers of Allāh; the place of praying for the angels of Allāh; the place where the revelation of Allāh descends; and the marketing place for those devoted to Allāh. Herein they earned mercy and herein they acquired Paradise by way of profit.
Therefore, who can abuse it when it has announced its departure and called out that it would leave! It had given news of its own destruction and the death of its people. By its hardship it set an example of their hardships. By its pleasures it created eagerness for the pleasures (of the next world). It brings ease in the evening and grief in the morning by way of persuasion, dissuasion, alarm and warning. People abuse it on the morning of their repentance but there are others who will praise it on the Day of Judgement. The world recalled to them the next life and they bore it in mind. It related to them (things of the next life) and they acknowledged them. It preached to them and they took lesson therefrom. 
 Every speaker and preacher manifests the force of his speaking in subjects in which he is well-versed. If he has to change the subject neither will his mind move nor will his tongue be able to speak out. But he whose intellect has the capability of adaptation and whose mind has the power of imagination can turn round his utterances in whatever manner he likes, and can show the excellence of speaking on whatever subject he desires. Consequently, when the tongue which had for so long been abusing the world and unveiling its deceitfulness starts praising the world it shows the same mastery of speaking and power of arguing that had ever been its chief distinction And then, the use of commendatory words does not alter the principle and although the ways are different the object remains the same.
