Sunan Ibn Majah Book 8, Hadith 1785

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنِ الأَعْمَشِ، عَنِ الْمَعْرُورِ بْنِ سُوَيْدٍ، عَنْ أَبِي ذَرٍّ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ مَا مِنْ صَاحِبِ إِبِلٍ وَلاَ غَنَمٍ وَلاَ بَقَرٍ لاَ يُؤَدِّي زَكَاتَهَا إِلاَّ جَاءَتْ يَوْمَ الْقِيَامَةِ أَعْظَمَ مَا كَانَتْ وَأَسْمَنَهُ تَنْطَحُهُ بِقُرُونِهَا وَتَطَؤُهُ بِأَخْفَافِهَا كُلَّمَا نَفِدَتْ أُخْرَاهَا عَادَتْ عَلَيْهِ أُولاَهَا ‏.‏ حَتَّى يُقْضَى بَيْنَ النَّاسِ ‏"‏ ‏.‏

Abu Dharr narrated that:the Messenger of Allah said: “There is no now owner of camels, sheeps or cattle who does not pay Zakat on them, but they will come on the Day of Resurrection as big and as fat as they ever were, butting him with their horns and trampling him with their hooves. Every time the of them has passed, the first of them will come back to him, until judgment is passed upon the people.”
