Fighting for the Cause of Allah (Jihaad)
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا حَاتِمٌ، عَنْ مُحَمَّدِ بْنِ يُوسُفَ، عَنِ السَّائِبِ بْنِ يَزِيدَ، قَالَ صَحِبْتُ طَلْحَةَ بْنَ عُبَيْدِ اللَّهِ وَسَعْدًا وَالْمِقْدَادَ بْنَ الأَسْوَدِ وَعَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ ـ رضى الله عنهم ـ فَمَا سَمِعْتُ أَحَدًا، مِنْهُمْ يُحَدِّثُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم، إِلاَّ أَنِّي سَمِعْتُ طَلْحَةَ يُحَدِّثُ عَنْ يَوْمِ أُحُدٍ.Narrated As-Sa'-ib bin Yazid:I was in the company of Talha bin 'Ubaidullah, Sa`d, Al-Miqdad bin Al-Aswad and `Abdur Rahman bin `Auf and I heard none of them narrating anything from Allah's Messenger (ﷺ) but Talha was talking about the day (of the battle) of Uhud
