Nahj al-Balāgha

ومن كتاب له (عليه السلام) إلى معاوية أيضا

To Mu‘āwiyah

أَمَّا بَعْدُ، فَإِنَّ الدُّنْيَا مَشْغَلَةٌ عَنْ غَيْرِهَا، وَلَمْ يُصِبْ صَاحِبُهَا مِنْهَا شَيْئاً إِلَّا فَتَحَتْ لَهُ حِرْصاً عَلَيْهَا، وَلَهَجاً بِهَا، وَلَنْ يَسْتَغْنِيَ صَاحِبُهَا بِمَا نَالَ فِيهَا عَمَّا لَمْ يَبْلُغْهُ مِنْهَا، وَمِنْ وَرَاءِ ذلِكَ فِرَاقُ مَا جَمَعَ، وَنَقْضُ مَا أَبْرَمَ! وَلَوِ اعْتَبَرْتَ بِمَا مَضَى حَفِظْتَ مَا بَقِيَ، وَالسَّلَامُ.

So now, this world turns away from the next one. He who is devoted to it achieves nothing from it except that it increases his greed and coveting for it. He who is devoted to it is not satisfied with what he gets from it because of what he has not got. Eventually, there is separation from what has been amassed, and a breaking of what has been strengthened. If you take a lesson from the past you can be safe in the future; and that is an end to the matter.
