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.
كُنْتُ أَلْبَسُ أَوْضَاحًا مِنْ ذَهَبٍ فَقُلْتُ يَا رَسُولَ اللَّهِ أَكَنْزٌ هُوَ فَقَالَ مَا بَلَغَ أَنْ تُؤَدَّى زَكَاتُهُ فَزُكِّيَ فَلَيْسَ بِكَنْزٍ
