Hadith 93:49
Narrated Ibn `Umar:
Allah's Messenger (ﷺ) sent an army unit headed by Usama bin Zaid and the people criticized his leadership. The Prophet (ﷺ) said (to the people), "If you are criticizing his leadership now, then you used to criticize his father's leadership before. By Allah, he (Usama's father) deserved the leadership and used to be one of the most beloved persons to me, and now his son (Usama) is one of the most beloved persons to me after him. " (See Hadith No. 745, Vol. 5)
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُسْلِمٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ دِينَارٍ، قَالَ سَمِعْتُ ابْنَ عُمَرَ ـ رضى الله عنهما ـ يَقُولُ بَعَثَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَعْثًا وَأَمَّرَ عَلَيْهِمْ أُسَامَةَ بْنَ زَيْدٍ، فَطُعِنَ فِي إِمَارَتِهِ، وَقَالَ " إِنْ تَطْعَنُوا فِي إِمَارَتِهِ فَقَدْ كُنْتُمْ تَطْعَنُونَ فِي إِمَارَةِ أَبِيهِ مِنْ قَبْلِهِ، وَايْمُ اللَّهِ إِنْ كَانَ لَخَلِيقًا لِلإِمْرَةِ، وَإِنْ كَانَ لَمِنْ أَحَبِّ النَّاسِ إِلَىَّ، وَإِنَّ هَذَا لَمِنْ أَحَبِّ النَّاسِ إِلَىَّ بَعْدَهُ "
