The sin of one who withholds Zakat
وَحَدَّثَنِي يُونُسُ بْنُ عَبْدِ الأَعْلَى الصَّدَفِيُّ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، حَدَّثَنِي هِشَامُ، بْنُ سَعْدٍ عَنْ زَيْدِ بْنِ أَسْلَمَ، فِي هَذَا الإِسْنَادِ بِمَعْنَى حَدِيثِ حَفْصِ بْنِ مَيْسَرَةَ إِلَى آخِرِهِ غَيْرَ أَنَّهُ قَالَ " مَا مِنْ صَاحِبِ إِبِلٍ لاَ يُؤَدِّي حَقَّهَا " . وَلَمْ يَقُلْ " مِنْهَا حَقَّهَا " . وَذَكَرَ فِيهِ " لاَ يَفْقِدُ مِنْهَا فَصِيلاً وَاحِدًا " . وَقَالَ " يُكْوَى بِهَا جَنْبَاهُ وَجَبْهَتُهُ وَظَهْرُهُ " .
This hadith has been narrated by Zaid b. Aslam with the same chain of transmitters except that he said:" None among the owners of camels who does not pay their due," but did not say" their due (Zakat) out of them." and he make a mention:" He did not miss a single young one out of them." and he said:" Their sides. their foreheads and their backs would be cauterised."
