Sahih al-Bukhari 3063
Narrated Anas bin Malik:
Allah's Messenger (ﷺ) delivered a sermon and said, "Zaid received the flag and was martyred, then Ja`far 
took it and was martyred, then `Abdullah bin Rawaha took it and was martyred, and then Khalid bin 
Al-Walid took it without being appointed, and Allah gave him victory." The Prophet (ﷺ) added, "I am not 
pleased (or they will not be pleased) that they should remain (alive) with us," while his eyes were 
shedding tears.
حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا ابْنُ عُلَيَّةَ، عَنْ أَيُّوبَ، عَنْ حُمَيْدِ بْنِ هِلاَلٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ خَطَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏
"‏ أَخَذَ الرَّايَةَ زَيْدٌ فَأُصِيبَ، ثُمَّ أَخَذَهَا جَعْفَرٌ فَأُصِيبَ، ثُمَّ أَخَذَهَا عَبْدُ اللَّهِ بْنُ رَوَاحَةَ فَأُصِيبَ، ثُمَّ أَخَذَهَا خَالِدُ بْنُ الْوَلِيدِ عَنْ غَيْرِ إِمْرَةٍ فَفُتِحَ عَلَيْهِ، وَمَا يَسُرُّنِي ـ أَوْ قَالَ مَا يَسُرُّهُمْ ـ أَنَّهُمْ عِنْدَنَا ‏"‏‏.‏ وَقَالَ وَإِنَّ عَيْنَيْهِ لَتَذْرِفَانِ‏.‏
