وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " إِذَا مَا رَبُّ النَّعَمِ لَمْ يُعْطِ حَقَّهَا ، تُسَلَّطُ عَلَيْهِ يَوْمَ الْقِيَامَةِ تَخْبِطُ وَجْهَهُ بِأَخْفَافِهَا " .
And the Prophet Muhammad (peace be upon him) said that whoever owns goats and does not pay their due zakat, on the Day of Resurrection those goats will be set upon him, trampling his face with their hooves.
