The Peak of Eloquence · Hadith 647 (#Passage #3)

أَمَّا وَصِيَّتِي: فَاللهَ لاَ تُشْرِكُوا بِهِ شَيْئاً، وَمُحَمَّداً فَلاَ تُضَيِّعُوا سُنَّتَهُ، أَقِيمُوا هذَيْن الْعَمُودَيْنِ، وَأَوْقِدُوا هذَيْنِ الْمِصْبَاحَيْنِ، وَخَلاَكُمْ ذَمٌّ مَالَمْ تَشْرُدُوا، حُمِّلَ كُلُّ امْرِىء مَجْهُودَهُ، وَخُفِّفَ عَنِ الْجَهَلَةِ، رَبٌّ رَحِيمٌ، وَدِينٌ قَوِيمٌ، وَإِمَامٌ عَلِيمٌ. أَنَا بِالاْمْسِ صَاحِبُكُمْ، وَأَنَا الْيَوْمَ عِبْرَةٌ لَكُمْ، وَغَداً مُفَارِقُكُمْ! غَفَرَ اللهُ لي وَلَكُمْ!

As for my last will, it is that concerning Allāh, do not believe in a partner for Him, and concerning Muḥammad (S), do not disregard his sunnah. Keep these two pillars and burn these two lamps. Till you are not divided, no evil will come to you. [2] Every one of you has to bear his own burden. It has been kept light for the ignorant. Allāh is Merciful. Faith is straight. The leader (Prophet) is the holder of knowledge. Yesterday I was with you; today I have become the object of a lesson for you; and tomorrow I shall leave you. Allāh may forgive me and you.
