حَدَّثَنَا أَبُو سَعِيدٍ، حَدَّثَنَا إِسْرَائِيلُ، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنِ الْحَارِثِ، عَنْ عَلِيٍّ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَوْ كُنْتُ مُؤَمِّرًا أَحَدًا دُونَ مَشُورَةِ الْمُؤْمِنِينَ لَأَمَّرْتُ ابْنَ أُمِّ عَبْدٍ
The Messenger of Allah (sallallahu alayhi wa sallam) said: ‘If I were to appoint anyone to a position of authority without consulting the believers, I would have appointed Ibn Umm Abd (Abdullah ibn Masood).’.
