Sunan an-Nasai
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا وَكِيعٌ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ السَّائِبِ، عَنْ رَجُلٍ، يُقَالُ لَهُ عُبَيْدُ اللَّهِ بْنُ مُعَيَّةَ قَالَ : أُصِيبَ رَجُلاَنِ مِنَ الْمُسْلِمِينَ يَوْمَ الطَّائِفِ، فَحُمِلاَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَأَمَرَ أَنْ يُدْفَنَا حَيْثُ أُصِيبَا . وَكَانَ ابْنُ مُعَيَّةَ وُلِدَ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم .
It was narrated that a man called 'Ubaidullah bin Mu'ayyah said: "Two Muslim men were killed on the day of At-Ta'if, and they were taken to the Messenger of Allah. He commanded that they be buried where they were killed." Ibn Mu'ayyah was born during the time of the Messenger of Allah.
