Leader of the righteous
Huzaifah narrates that the Messenger of Allah (ص) said:
﴿ عَلِيٌّ أَمِيرُ الْبَرَرَةِ، وَقَاتِلُ الفَجَرَةِ، مَنْصُورُ مَنْ نَصَـرَهُ، مَـخْذُولُ مَنْ خَذَلَهُ، أَلَا وَإِنَّ الْـحَقَّ مَعَهُ وَيَتْبَعُهُ، أَلَا فَمِيلُوا مَعَهُ ﴾
“Ali is the leader of the virtuous, and the killer of the wicked. The one who supports him is victorious, and the one who is disloyal to him will be disgraced. Indeed, the truth is with him and follows him. Be aware that your inclination and direction should be centered around him.”
Ibn Marduyeh Esfahani, Al-Manaqib, page 163; Kharazmi, Al-Manaqib, page 177.
Hakim narrates in Al-Mustadrak (V.3, p.129) from Jabir ibn Abdullah that he said: I heard the Messenger of Allah (s.a.w.a.) say aloud while holding the arm of Ali-ibn-Abi Talib (a.s.), “This is Ali, leader of the righteous and killer of the wicked. The one who stands to help him will be victorious and the one who humiliates him will be disgraced.”
And in Al-Jami' as-Saghir (Suyuti, V.2, p.177) it is stated: “Ali is the Imam of the virtuous and the killer of evildoers. Whoever supports him will be supported and whoever disgraces him will be disgraced.” As per narration from Hakim (as a good and acceptable hadith)
