Sahih Muslim 2426 a
Ibn 'Umar reported that Allah's Messenger (ﷺ) sent an expedition and appointed Usama b. Zaid as its chief. The people objected to his command, whereupon Allah's Messenger (ﷺ) stood up and said:
You object to his command and before this you objected to the command of his father (Zaid). By Allah, he was fit as the commander and he was one of the dearest of persons to me and after him, behold! this one (Usama) is one of the dearest of persons to me.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَيَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ قَالَ يَحْيَى بْنُ يَحْيَى
 أَخْبَرَنَا وَقَالَ الآخَرُونَ، حَدَّثَنَا - إِسْمَاعِيلُ، - يَعْنُونَ ابْنَ جَعْفَرٍ - عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ،
 أَنَّهُ سَمِعَ ابْنَ عُمَرَ، يَقُولُ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَعْثًا وَأَمَّرَ عَلَيْهِمْ أُسَامَةَ
 بْنَ زَيْدٍ فَطَعَنَ النَّاسُ فِي إِمْرَتِهِ فَقَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏
"‏ إِنْ تَطْعَنُوا
 فِي إِمْرَتِهِ فَقَدْ كُنْتُمْ تَطْعَنُونَ فِي إِمْرَةِ أَبِيهِ مِنْ قَبْلُ وَايْمُ اللَّهِ إِنْ كَانَ لَخَلِيقًا لِلإِمْرَةِ وَإِنْ
 كَانَ لَمِنْ أَحَبِّ النَّاسِ إِلَىَّ وَإِنَّ هَذَا لَمِنْ أَحَبِّ النَّاسِ إِلَىَّ بَعْدَهُ ‏"‏ ‏.‏
