وَقَالَ مَالِك فِي رَجُلٍ كَانَتْ لَهُ عَشَرَةُ دَنَانِيرَ ، فَتَجَرَ فِيهَا فَحَالَ عَلَيْهَا الْحَوْلُ وَقَدْ بَلَغَتْ عِشْرِينَ دِينَارًا : أَنَّهُ يُزَكِّيهَا مَكَانَهَا وَلَا يَنْتَظِرُ بِهَا أَنْ يَحُولَ عَلَيْهَا الْحَوْلُ مِنْ يَوْمَ بَلَغَتْ مَا تَجِبُ فِيهِ الزَّكَاةُ ، لِأَنَّ الْحَوْلَ قَدْ حَالَ عَلَيْهَا وَهِيَ عِنْدَهُ عِشْرُونَ ثُمَّ لَا زَكَاةَ فِيهَا حَتَّى يَحُولَ عَلَيْهَا الْحَوْلُ مِنْ يَوْمَ زُكِّيَتْ
Imam Malik, may Allah have mercy on him, said: A person had ten dinars, from which he traded, and by the end of the year they reached twenty dinars, then zakat will be obligatory on it. It will not be that he waits for a year to pass from when it reached twenty dinars. Because when the year passed, he had twenty dinars, then zakat will not be due on it again until another year passes.
