Jami` at-Tirmidhi, Book 36, Hadith 63 (In-Book) ⓘ
Sa'd Bin Malik said: "I was the first man among the Arabs to shoot an arrow in Allah's cause. I saw that we battled along with the Messenger of Allah(s.a.w) and there was no food for us but Al-Hubla and this Samur, such that one of us would leave droppings like the droppings of a sheep. Then Banu Asad appeared wanting to instruct me in religion. I would be a loser and have wasted my efforts."
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ أَبِي خَالِدٍ، حَدَّثَنَا قَيْسٌ، قَالَ سَمِعْتُ سَعْدَ بْنَ مَالِكٍ، يَقُولُ إِنِّي أَوَّلُ رَجُلٍ مِنَ الْعَرَبِ رَمَى بِسَهْمٍ فِي سَبِيلِ اللَّهِ وَلَقَدْ رَأَيْتُنَا نَغْزُو مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَمَا لَنَا طَعَامٌ إِلاَّ الْحُبُلَةَ وَهَذَا السَّمُرَ حَتَّى إِنَّ أَحَدَنَا لَيَضَعُ كَمَا تَضَعُ الشَّاةُ ثُمَّ أَصْبَحَتْ بَنُو أَسَدٍ يُعَزِّرُونِي فِي الدِّينِ لَقَدْ خِبْتُ إِذًا وَضَلَّ عَمَلِي . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ . وَفِي الْبَابِ عَنْ عُتْبَةَ بْنِ غَزْوَانَ .
