Sa'd Bin Abi Waqqas said:

"I was among the first men who spilled blood in Allah's cause, and I was among the first men to shoot an arrow in Allah's cause. I saw battles with troops of the Companions of Muhammad ﷺ. We had nothing to eat except leaves of trees and Al-Hublah, such that one of us would leave droppings like the droppings of sheep and camels. Now Banu Asad have appeared wanting to instruct me in religion, ( then) I would be a loser and have wasted my efforts."

حَدَّثَنَا عُمَرُ بْنُ إِسْمَاعِيلَ بْنِ مُجَالِدِ بْنِ سَعِيدٍ، حَدَّثَنَا أَبِي، عَنْ بَيَانٍ، عَنْ قَيْسِ بْنِ أَبِي حَازِمٍ، قَالَ سَمِعْتُ سَعْدَ بْنَ أَبِي وَقَّاصٍ، يَقُولُ إِنِّي لأَوَّلُ رَجُلٍ أَهْرَاقَ دَمًا فِي سَبِيلِ اللَّهِ وَإِنِّي لأَوَّلُ رَجُلٍ رَمَى بِسَهْمٍ فِي سَبِيلِ اللَّهِ وَلَقَدْ رَأَيْتُنِي أَغْزُو فِي الْعِصَابَةِ مِنْ أَصْحَابِ مُحَمَّدٍ ﷺ مَا نَأْكُلُ إِلاَّ وَرَقَ الشَّجَرِ وَالْحُبُلَةِ حَتَّى إِنَّ أَحَدَنَا لَيَضَعُ كَمَا تَضَعُ الشَّاةُ أَوِ الْبَعِيرُ وَأَصْبَحَتْ بَنُو أَسَدٍ يُعَزِّرُونِي فِي الدِّينِ لَقَدْ خِبْتُ إِذًا وَضَلَّ عَمَلِي .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ مِنْ حَدِيثِ بَيَانٍ .
