NASAI-KUBRA 4424:
from ʿUbādah b. al-Ṣāmit —
"On the day of Hunain the Messenger of Allah took a hair from the side of a camel and said: 'O you people, it is not permissible for me to take even the equivalent of this from the Fay' that Allah has bestowed upon you, except the Khumus, and the Khumus will come back to you." (Sahih) Abu 'Abdur-Rahman (An-Nasa'i) said: Abu Sallam's name is Mamtur and he is Ethiopian, and Abu Umamah's name is Sudai bin 'Ajlan. (Using translation from Nasāʾī 4138)
الكبرى للنسائي ٤٤٢٤:
عن عباده بن الصامت —
أَخَذَ النَّبِيُّ ﷺ يَوْمَ حُنَيْنٍ وَبَرَةً مِنْ جَنْبِ بَعِيرٍ فَقَالَ «أَيُّهَا النَّاسُ إِنَّهُ لَا يَحِلُّ لِي مِمَّا أَفَاءَ اللهُ عَلَيْكُمْ قَدْرُ هَذِهِ إِلَّا الْخُمُسُ وَالْخُمُسُ مَرْدُودٌ عَلَيْكُمْ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ اسْمُ أَبِي سَلَامٍ مَمْطُورٌ وَاسْمُ أَبِي أُمَامَةَ صُدَيُّ بْنُ عَجْلَانَ
