"The Messenger of Allah sent me to Yemen, and he commanded me to take from every forty cows, a cow in its third year, and from every thirty, a Tabi '(two-year-old), and from every person who had reached the age of puberty a Dinar or is equivalent in Maafir." (Daif)
مُعَاذٌ بَعَثَنِي رَسُولُ اللَّهِ ﷺ إِلَى الْيَمَنِ فَأَمَرَنِي أَنْ آخُذَ مِنْ كُلِّ أَرْبَعِينَ بَقَرَةً ثَنِيَّةً وَمِنْ كُلِّ ثَلاَثِينَ تَبِيعًا وَمِنْ كُلِّ حَالِمٍ دِينَارًا أَوْ عِدْلَهُ مَعَافِرَ
