The Peak of Eloquence · Hadith 297 (#Passage #3)
Chapter 83 | Al-Gharra (literally, "the brilliant"), in which Ali enjoined people to piety
وَأَشْهَدُ أَنَّ مُحَمَّداً صلى الله عليه وآله عَبْدُهُ وَرَسُولُهُ، أَرْسَلَهُ لاِنْفَاذِ أَمْرِهِ، وَإِنْهَاءِ عُذْرِهِ وَتَقْدِيمِ نُذُرِهِ
And I stand witness that Muḥammad (blessing of Allāh be on him and his progeny) is His slave and His Prophet. He sent him for enforcement of His commends, for exhausting His pleas and for presenting warnings (against eternal punishment).
