"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.  

أُصِيبَ رَجُلاَنِ مِنَ الْمُسْلِمِينَ يَوْمَ الطَّائِفِ فَحُمِلاَ إِلَى رَسُولِ اللَّهِ ﷺ فَأَمَرَ أَنْ يُدْفَنَا حَيْثُ أُصِيبَا وَكَانَ ابْنُ مُعَيَّةَ وُلِدَ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ  

That the Prophet commanded that those who had been killed at Uhud should be taken back to the place where they fell; they had been brought to Al-Madinah.  

عَنْ نُبَيْحٍ الْعَنَزِيِّ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ أَنَّ النَّبِيَّ ﷺ أَمَرَ بِقَتْلَى أُحُدٍ أَنْ يُرَدُّوا إِلَى مَصَارِعِهِمْ وَكَانُوا قَدْ نُقِلُوا إِلَى الْمَدِينَةِ  

"Bury the slain where they fell."  

عَنْ نُبَيْحٍ الْعَنَزِيِّ عَنْ جَابِرٍ أَنَّ النَّبِيَّ ﷺ قَالَ ادْفِنُوا الْقَتْلَى فِي مَصَارِعِهِمْ
