أَخْبَرَنَا أَحْمَدُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ مَسْرُوقٍ، عَنْ مُعَاذٍ، قَالَ لَمَّا بَعَثَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلَى الْيَمَنِ أَمَرَهُ أَنْ يَأْخُذَ مِنْ كُلِّ ثَلاَثِينَ مِنَ الْبَقَرِ تَبِيعًا أَوْ تَبِيعَةً وَمِنْ كُلِّ أَرْبَعِينَ مُسِنَّةً وَمِنْ كُلِّ حَالِمٍ دِينَارًا أَوْ عِدْلَهُ مَعَافِرَ ‏.‏
