عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ رَأَيْتُ الْمَغَانِمَ تُجْزَأُ خَمْسَةَ أَجْزَاءٍ ثُمَّ يُسْهَمُ عَلَيْهَا فَمَا كَانَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَهُوَ لَهُ يَتَخَيَّرُ
It is narrated from Sayyiduna Abdullah bin Umar, may Allah be pleased with them both, he says: I saw that the spoils of war were divided into five parts, then those parts were further divided. The portion that belonged to the Messenger of Allah, peace and blessings be upon him, he himself would select for it (i.e., he would give to whomever he wished and withhold from whomever he wished).
