Sunan an-Nasai
أَخْبَرَنَا عِيسَى بْنُ حَمَّادٍ، قَالَ أَنْبَأَنَا اللَّيْثُ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَمْرِو بْنِ يَحْيَى بْنِ عُمَارَةَ، عَنْ أَبِيهِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لَيْسَ فِيمَا دُونَ خَمْسَةِ ذَوْدٍ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسَةِ أَوَاقٍ صَدَقَةٌ وَلَيْسَ فِيمَا دُونَ خَمْسَةِ أَوْسُقٍ صَدَقَةٌ " .
It was narrated from Abu Saeed Al-Khudri that the Messenger of Allah said: "No Sadaqah is due on less than five Dhawd (head of camel), and no Sadaqah is due on less than five Awaq, and no Sadaqah is due on less than five Awsuq."
