وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ مُعَاذِ بْنِ جَبَلٍ، أَنَّهُ قَالَ الْغَزْوُ غَزْوَانِ فَغَزْوٌ تُنْفَقُ فِيهِ الْكَرِيمَةُ وَيُيَاسَرُ فِيهِ الشَّرِيكُ وَيُطَاعُ فِيهِ ذُو الأَمْرِ وَيُجْتَنَبُ فِيهِ الْفَسَادُ فَذَلِكَ الْغَزْوُ خَيْرٌ كُلُّهُ وَغَزْوٌ لاَ تُنْفَقُ فِيهِ الْكَرِيمَةُ وَلاَ يُيَاسَرُ فِيهِ الشَّرِيكُ وَلاَ يُطَاعُ فِيهِ ذُو الأَمْرِ وَلاَ يُجْتَنَبُ فِيهِ الْفَسَادُ فَذَلِكَ الْغَزْوُ لاَ يَرْجِعُ صَاحِبُهُ كَفَافًا ‏.‏

Yahya related to me from Malik from Yahya ibn Said that Muadh ibnJabal said, "There are two military expeditions. There is one militaryexpedition in which valuables are spent, the contributor is willing,the authorities are obeyed, and corruption is avoided. That militaryexpedition is all good. There is a military expedition in whichvaluables are not spent, the contributor is not willing, theauthorities are not obeyed, and corruption is not avoided. The one whofights in that military expedition does not return with reward." Translation Not Available
