وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ أَبِي صَالِحٍ السَّمَّانِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ كَانَ يَقُولُ مَنْ كَانَ عِنْدَهُ مَالٌ لَمْ يُؤَدِّ زَكَاتَهُ مُثِّلَ لَهُ يَوْمَ الْقِيَامَةِ شُجَاعًا أَقْرَعَ لَهُ زَبِيبَتَانِ يَطْلُبُهُ حَتَّى يُمْكِنَهُ يَقُولُ أَنَا كَنْزُكَ ‏.‏

Yahya related to me from Malik from Abdullah ibn Dinar fromAbu's-Salih as-Samman that Abu Hurayra used to say, "Anyone who haswealth on which he has not paid zakat will, on the day of rising, findhis wealth made to resemble a whiteheaded serpent with a sac of venomin each cheek which will seek him out until it has him in its power,saying, 'I am the wealth that you had hidden away.'
