Messenger of Allah ﷺ said, "Whoever is made wealthy by Allah and does not pay the Zakat of his wealth, then on the Day of Resurrection his wealth will be made like a baldheaded poisonous male snake with two black spots over the eyes. The snake will encircle his neck and bite his cheeks and say, 'I am your wealth, I am your treasure.' " Then the Prophet ﷺ recited the holy verses:-- 'Let not those who withhold . . .' (to the end of the verse). (3.180).
قَالَ رَسُولُ اللَّهِ ﷺ مَنْ آتَاهُ اللَّهُ مَالاً فَلَمْ يُؤَدِّ زَكَاتَهُ مُثِّلَ لَهُ يَوْمَ الْقِيَامَةِ شُجَاعًا أَقْرَعَ لَهُ زَبِيبَتَانِ يُطَوَّقُهُ يَوْمَ الْقِيَامَةِ ثُمَّ يَأْخُذُ بِلِهْزِمَتَيْهِ يَعْنِي شِدْقَيْهِ ثُمَّ يَقُولُ أَنَا مَالُكَ أَنَا كَنْزُكَ ثُمَّ تَلاَ {لاَ يَحْسِبَنَّ الَّذِينَ يَبْخَلُونَ} الآيَةَ
