The Peak of Eloquence · Hadith 1485 (#Passage #294)

وَلَا تَنْقُضْ سُنَّةً صَالِحَةً عَمِلَ بِهَا صُدُورُ هَذِهِ الْأُمَّةِ، وَاجْتَمَعتْ بِهَا الْأُلْفَةُ، وَصَلَحَتْ عَلَيْهَا الرَّعِيَّةُ، وَلَا تُحْدِثَنَّ سُنَّةً تَضُرُّ بِشَيْءٍ مِنْ مَاضِي تِلْكَ السُّنَنِ، فَيَكُونَ الْأَجْرُ لِمَنْ سَنَّهَا، وَالْوِزْرُ عَلَيْكَ بِمَا نَقَضْتَ مِنْهَا. وَأَكْثِرْ مُدَارَسَةَ الَعُلَمَاءِ، وَمُنَاقَشَةَ [وَمُنَافَثَةَ] الْحُكَمَاءِ، فِي تَثْبِيتِ مَا صَلَحَ عَلَيْهِ أَمْرُ بِلَادِكَ، وَإِقَامَةِ مَا اسْتَقَامَ بِهِ النَّاسُ قَبْلَكَ.

Do not discontinue the good lives in which the earlier people of this community had been acting, by virtue of which there was general unity and through which the subjects prospered. Do not innovate any line of action which injures these earlier ways because (in that case) the reward for those who had established those ways will continue, but the burden for discontinuing them will be on you. Keep on increasing your conversations with the scholars and discussions with the wise to stabilize the prosperity of the areas under you, and to continue with that in which the earlier people had remained steadfast.
