The Messenger of Allah ﷺ said: “If I were to appoint anyone to a position of authority without consulting (the believers), I would have appointed Ibn Umm ʿAbd (ʿAbdullah bin Masʿood).ʿ (Using translation from Aḥmad 739)
قَالَ رَسُولُ اللَّهِ ﷺ «لَوْ كُنْتُ مُسْتَخْلِفًا أَحَدًا مِنْ غَيْرِ مَشُورَةٍ لَاسْتَخْلَفْتُ عَلَيْهِمُ ابْنَ أُمِّ عَبْدٍ»
