The Virtue of `Abdullah ibn Mas`ud (ra)
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الْحَارِثِ، عَنْ عَلِيٍّ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ لَوْ كُنْتُ مُسْتَخْلِفًا أَحَدًا عَنْ غَيْرِ مَشُورَةٍ لاَسْتَخْلَفْتُ ابْنَ أُمِّ عَبْدٍ .
It was narrated that 'Ali said: "The Messenger of Allah said: 'If I were to appoint anyone as my successor without consulting anyone, I would have appointed Ibn Umm 'Abd.'"
