"If Allah gives a person wealth and he does not pay Zakah on it, his wealth will appear to him on the Day of Resurrection as a bald-heated Shuja'a with two dots above its eyes. It will take hold of the corners of his mouth on the Day of Resurrection and will say: 'I am your wealth, I am your hoarded treasure.' The he recited this verse: 'And let not those who covetously withhold of that which Allah has bestowed on them of His Bounty (wealth) and think that it is good for them (and so they do not pay the obligatory Zakah)."'
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ آتَاهُ اللَّهُ ﷻ مَالاً فَلَمْ يُؤَدِّ زَكَاتَهُ مُثِّلَ لَهُ مَالُهُ يَوْمَ الْقِيَامَةِ شُجَاعًا أَقْرَعَ لَهُ زَبِيبَتَانِ يَأْخُذُ بِلِهْزِمَتَيْهِ يَوْمَ الْقِيَامَةِ فَيَقُولُ أَنَا مَالُكَ أَنَا كَنْزُكَ ثُمَّ تَلاَ هَذِهِ الآيَةَ { وَلاَ يَحْسَبَنَّ الَّذِينَ يَبْخَلُونَ بِمَا آتَاهُمُ اللَّهُ مِنْ فَضْلِهِ } الآيَةَ
