وَإِنْ لَمْ يَكُنْ عِنْدَهُ مِنَ الْعُرُوضِ وَالنَّقْدِ إِلَّا وَفَاءُ دَيْنِهِ ، فَلَا زَكَاةَ عَلَيْهِ حَتَّى يَكُونَ عِنْدَهُ مِنَ النَّاضِّ فَضْلٌ عَنْ دَيْنِهِ مَا تَجِبُ فِيهِ الزَّكَاةُ ، فَعَلَيْهِ أَنْ يُزَكِّيَهُ
Imam Malik, may Allah have mercy on him, said: If cash and goods combined are equal to his debt, then zakat will not be obligatory upon him until the cash exceeds his debt and reaches the nisab. As long as this is the case, he should give zakat.
