Sahih Muslim 1769 d
This tradition has been narrated by Hishim through the same chain of transmitters with a little difference in the wording. He said:
(His wound) began to bleed that very night and it continued to bleed until he died. He has made the addition that it was then that (a non-believing) poet said: 
Hark, O Sa'd, Sa'd of Banu Mu'adh, 
What have the Quraiaa and Nadir done? 
By thy life! Sa'd b. Mu'adh>br> Was steadfast on the morn they departed. 
You have left your cooking-pot empty, 
While the cooking-pot of the people is hot and boiling. 
Abu Hubab the nobleman has said, 
O Qainuqa', do not depart. 
They were weighty in their country 
just aa rocks are weighty in Maitan.
وَحَدَّثَنَا عَلِيُّ بْنُ الْحُسَيْنِ بْنِ سُلَيْمَانَ الْكُوفِيُّ، حَدَّثَنَا عَبْدَةُ، عَنْ هِشَامٍ، بِهَذَا الإِسْنَادِ نَحْوَهُ غَيْرَ أَنَّهُ قَالَ فَانْفَجَرَ مِنْ لَيْلَتِهِ فَمَازَالَ يَسِيلُ حَتَّى مَاتَ وَزَادَ فِي الْحَدِيثِ قَالَ فَذَاكَ حِينَ يَقُولُ الشَّاعِرُ أَلاَ يَا سَعْدُ سَعْدَ بَنِي مُعَاذٍ فَمَا فَعَلَتْ قُرَيْظَةُ وَالنَّضِيرُ لَعَمْرُكَ إِنَّ سَعْدَ بَنِي مُعَاذٍ غَدَاةَ تَحَمَّلُوا لَهُوَ الصَّبُورُ تَرَكْتُمْ قِدْرَكُمْ لاَ شَىْءَ فِيهَا وَقِدْرُ الْقَوْمِ حَامِيَةٌ تَفُورُ وَقَدْ قَالَ الْكَرِيمُ أَبُو حُبَابٍ أَقِيمُوا قَيْنُقَاعُ وَلاَ تَسِيرُوا وَقَدْ كَانُوا بِبَلْدَتِهِمْ ثِقَالاً كَمَا ثَقُلَتْ بِمَيْطَانَ الصُّخُورُ
