Sunan Abu Dawud 1564
Zakat (Kitab Al-Zakat)
حَدَّثَنَا مُحَمَّدُ بْنُ عِيسَى، حَدَّثَنَا عَتَّابٌ، - يَعْنِي ابْنَ بَشِيرٍ - عَنْ ثَابِتِ بْنِ عَجْلاَنَ، عَنْ عَطَاءٍ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ كُنْتُ أَلْبَسُ أَوْضَاحًا مِنْ ذَهَبٍ فَقُلْتُ يَا رَسُولَ اللَّهِ أَكَنْزٌ هُوَ فَقَالَ " مَا بَلَغَ أَنْ تُؤَدَّى زَكَاتُهُ فَزُكِّيَ فَلَيْسَ بِكَنْزٍ " .
Narrated Umm Salamah, Ummul Mu'minin: I used to wear gold ornaments. I asked: Is that a treasure (kanz), Messenger of Allah? He replied: whatever reaches a quantity on which zakat is payable is not a treasure (kanz) when the zakat is paid
