أُوصِيكُمَا، وَجَمِيعَ وَلَدِي وَأَهْلِي وَمَنْ بَلَغَهُ كِتَابِي، بِتَقْوَى اللهِ، وَنَظْمِ أَمْرِكُمْ، وَصَلَاحِ ذَاتِ بَيْنِكُمْ، فَإِنِّي سَمِعْتُ جَدَّكُمَا (صلى الله عليه وآله) يَقُولُ: «صَلَاحُ ذَاتِ الْبَيْنِ أَفْضَلُ مِنْ عَامَّةِ الصَّلَاةِ وَالصِّيَامِ».
I advise you (both) and all my children and members of my family and everyone whom my writing reaches, to fear Allāh, to keep your affairs in order, and to maintain good relations among yourselves for I have heard your Grandfather (the Holy Prophet – S) saying, “Improvement of mutual differences is better than general prayers and fastings.”
