وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا
قَالَتْ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَا خَالَطَتِ الزَّكَاةُ مَالًا قَطُّ إِلَّا أَهْلَكَتْهُ»
Aishah said she heard God’s messenger say, “zakat is never mingled with any property without destroying it.” Shafii, Bukhari in his Tarikh, and al-Humaidi transmitted it, al-Humaidl adding He said, “Sadaqa will have been incumbent on you and you will not pay it, so what is forbidden will destroy what is lawful.” Those who hold that the zakat is connected with the property itself have used this as an argument.
It is given thus in al-Muntaqa. Baihaqi transmitted in Shuab al-iman from Ahmad ibn Hanbal with, his isnad to Aishah, and Ahmad said “mingled” means that a man accepts zakat when he is opulent or rich, whereas it is only for the poor.
