Sahih al-Bukhari, Volume 4, Book 52, Hadith 55 (USC-MSA) ⓘ

Narrated Anas bin Malik: The Prophet delivered a sermon and said, "Zaid took the flag and was martyred, and then Ja`far took the flag and was martyred, and then `Abdullah bin Rawaha took the flag and was martyred too, and then Khalid bin Al-Walid took the flag though he was not appointed as a commander and Allah made him victorious." The Prophet further added, "It would not please us to have them with us." Aiyub, a sub-narrator, added, "Or the Prophet, shedding tears, said, 'It would not please them to be with us.'"

حَدَّثَنَا يُوسُفُ بْنُ يَعْقُوبَ الصَّفَّارُ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ أَيُّوبَ، عَنْ حُمَيْدِ بْنِ هِلاَلٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ خَطَبَ النَّبِيُّ 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 لَهُ ـ وَقَالَ ـ مَا يَسُرُّنَا أَنَّهُمْ عِنْدَنَا ‏"‏‏.‏ قَالَ أَيُّوبُ أَوْ قَالَ ‏"‏ مَا يَسُرُّهُمْ أَنَّهُمْ عِنْدَنَا ‏"‏‏.‏ وَعَيْنَاهُ تَذْرِفَانِ‏.‏
