The Peak of Eloquence · Hadith 1960 (#Passage #319)

فَقَالَ (عليه السلام) : إِنَّ سَعِيداً وَعَبْدَ اللهِ بْنَ عُمَرَ لَمْ يَنْصُرَا الْحَقَّ، وَلَمْ يَخْذُلَا الْبَاطِلَ.

whereupon Amīr al-mu’minīn, peace be upon him, said: Verily, Sa‘d and ‘Umar have neither sided with Right nor forsaken Wrong. [1]
