" لَيْسَ فِي حَبٍّ وَلاَ تَمْرٍ صَدَقَةٌ حَتَّى يَبْلُغَ خَمْسَةَ أَوْسُقٍ وَلاَ فِيمَا دُونَ خَمْسِ ذَوْدٍ وَلاَ فِيمَا دُونَ خَمْسِ أَوَاقٍ صَدَقَةٌ "
It was narrated from Abu Sa'eed Al-Khudri that the Prophet said: "No Sadaqah is due on grains or dates unless the amount reaches five Awauq, nor on less than five Dhawd, nor on less than five Awaq."
