“O Aktham! Fight alongside people other than your own, it will improve your attitude and make you generous to your companions. O Aktham, the best number of companions is four, the best number of troops on an expedition is four hundred, the best number of an army is four thousand, and twelve thousand will never be overpowered because of their small number.”
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لأَكْثَمَ بْنِ الْجَوْنِ الْخُزَاعِيِّ يَا أَكْثَمُ اغْزُ مَعَ غَيْرِ قَوْمِكَ يَحْسُنْ خُلُقُكَ وَتَكْرُمْ عَلَى رُفَقَائِكَ يَا أَكْثَمُ خَيْرُ الرُّفَقَاءِ أَرْبَعَةٌ وَخَيْرُ السَّرَايَا أَرْبَعُمِائَةٍ وَخَيْرُ الْجُيُوشِ أَرْبَعَةُ آلاَفٍ وَلَنْ يُغْلَبَ اثْنَا عَشَرَ أَلْفًا مِنْ قِلَّةٍ
