وَعَنْ بَهْزِ بْنِ حَكِيمٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«فِي كُلِّ سَائِمَةِ إِبِلٍ: فِي أَرْبَعِينَ بِنْتُ لَبُونٍ، لَا تُفَرَّقُ إِبِلٌ عَنْ حِسَابِهَا، مَنْ أَعْطَاهَا مُؤْتَجِرًا بِهَا فَلَهُ أَجْرُهُ، وَمَنْ مَنَعَهَا فَإِنَّا آخِذُوهَا وَشَطْرَ مَالِهِ، عَزْمَةً مِنْ عَزَمَاتِ رَبِّنَا، لَا يَحِلُّ لِآلِ مُحَمَّدٍ مِنْهَا شَيْءٌ»
“For every forty camels, one ‘bint labun’ (a young female camel which is two years old and already starting the third year), is due as Zakah. No camel is to be separated from the rest of the camels (i.e. the jointly owned live stock as mentioned above). Whoever gives it willingly, seeking his reward from Allah, will be rewarded.
(However) if someone refrains from paying it, it will be taken from him (by force) along with part of his property (as punishment), for it is a right of Allah. None of it is lawful for the family of Muhammad (sallallahu alayhi wa sallam).” Related by Ahmad, An-Nasai, Abu Dawud and Al-Hakim rendered it Sahih. And Ash-Shafiee conditioned ruling by it depending on its authenticity.
