Ibn ‘Awn said “I asked Muhammad about the portion of the prophet ﷺ and safi. He replied “A portion was taken for him along with the Muslims, even if he did not attend (the battle) and safi (special portion) was taken from the fifth before everything.” (Using translation from Abū Dāʾūd 2992)
عَنْ سَهْمِ النَّبِيِّ ﷺ وَالصَّفِيِّ قَالَ كَانَ يُضْرَبُ لَهُ بِسَهْمٍ مَعَ الْمُسْلِمِينَ وَإِنْ لَمْ يَشْهَدْ وَالصَّفِيُّ يُؤْخَذُ لَهُ رَأْسٌ مِنَ الْخُمُسِ قَبْلَ كُلِّ شَيْءٍ
