Nahj al-Balāgha|Volume 1|Book 2|Chapter 64
وَعِنْدِي السَّيْفُ الَّذِي أَعْضَضْتُهُ بِجَدِّكَ وَخَالِكَ وَأَخِيكَ فِي مَقَامٍ وَاحِدٍ، وَإِنَّكَ وَاللهِ مَا عَلِمْتُ الْأَغْلَفُ الْقَلْبِ، الْمُقَارِبُ الْعَقْلِ، وَالْأَوْلَى أَنْ يُقَالَ لَكَ: إِنَّكَ رَقِيتَ سُلَّماً أَطْلَعَكَ مَطْلَعَ سُوءٍ عَلَيْكَ لَا لَكَ، لِأَنَّكَ نَشَدْتَ غَيْرَ ضَالَّتِكَ، وَرَعَيْتَ غَيْرَ سَائِمَتِكَ، وَطَلَبْتَ أَمْراً لَسْتَ مِنْ أَهْلِهِ وَلَا فِي مَعْدِنِهِ.
(Remember) I have still the sword with which I dispatched your grandfather, your mother’s brother and your brother to one and the same place. By Allāh, I know what you are. Your heart is sheathed and your intelligence is weak. It is better to say that you have ascended to where you view a bad scene which is against you, not in your favour, because you are searching a thing lost by someone else, you are tending someone else’s cattle and you are hankering after a thing which is not yours nor have you any attachment with it.
