Mishkat al-Masabih
‘Ali said that God’s messenger put him in charge of his sacrificial I camels, telling him to give their flesh, skins and saddle-cloths as sadaqa,but not to give anything to the butcher, saying he would pay him himself. Bukhari and Muslim.
وَعَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ: أَمَرَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ أَقُومَ عَلَى بُدْنِهِ وَأَنْ أَتَصَدَّقَ بِلَحْمِهَا وَجُلُودِهَا وَأَجِلَّتِهَا وَأَنْ لَا أُعْطِيَ الْجَزَّارَ مِنْهَا قَالَ: «نَحْنُ نُعْطِيهِ مِنْ عِنْدِنَا»
