Ibn Awn reported,

I asked Muhammad about the share of the Prophet ﷺ and the safi. He said, "A share would be allotted to him along with the Muslims, even if he was not present, and the safi was taken for him as one head from the khumus before anything else."

حدثنا محمد بن بشار حدثنا أبو عاصم وأزهر قالا

حدثنا ابن عون قال

سألت محمدا عن سهم النبي ﷺ والصفي قال كان يضرب له بسهم مع المسلمين وإن لم يشهد والصفي يؤخذ له رأس من الخمس قبل كل شيء
