Narrated `Abdullah bin `Umar:The Prophet (ﷺ) sent an army under the command of Usama bin Zaid. When some people criticized his leadership, the Prophet (ﷺ) said, "If you are criticizing Usama's leadership, you used to criticize his father's leadership before. By Allah! He was worthy of leadership and was one of the dearest persons to me, and (now) this (i.e. Usama) is one of the dearest to me after him (i.e. Zaid).
حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، حَدَّثَنَا سُلَيْمَانُ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ بَعَثَ النَّبِيُّ صلى الله عليه وسلم بَعْثًا، وَأَمَّرَ عَلَيْهِمْ أُسَامَةَ بْنَ زَيْدٍ، فَطَعَنَ بَعْضُ النَّاسِ فِي إِمَارَتِهِ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم " إِنْ تَطْعُنُوا فِي إِمَارَتِهِ فَقَدْ كُنْتُمْ تَطْعُنُونَ فِي إِمَارَةِ أَبِيهِ مِنْ قَبْلُ، وَايْمُ اللَّهِ، إِنْ كَانَ لَخَلِيقًا لِلإِمَارَةِ، وَإِنْ كَانَ لَمِنْ أَحَبِّ النَّاسِ إِلَىَّ، وَإِنَّ هَذَا لَمِنْ أَحَبِّ النَّاسِ إِلَىَّ بَعْدَهُ ".
