أُوصِيكُمَا بِتَقْوَى اللهِ، وَأَلَّا تَبْغِيَا الدُّنْيَا وَإِنْ بَغَتْكُمَا، وَلَا تَأْسَفَا عَلَى شَيْ‏ءٍ مِنْهَا زُوِيَ عَنْكُمَا، وَقُولَا بِالْحَقِّ، وَاعْمَلَا لِلْأَجْرِ، وَكُونَا لِلظَّالِمِ خَصْماً، وَلِلْمَظْلُومِ عَوْناً.
I advise you (both) to fear Allāh and that you should not hanker after the (pleasures of this) world even though it may run after you. Do not be sorry for anything of this world that you have been denied. Speak the truth and act (in expectation) for reward. Be an enemy of the oppressor and helper of the oppressed.
