وَعَنْ عَبْدِ اَلرَّحْمَنِ بْنِ الْبَيْلَمَانِيِّ; { أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -قَتَلَ مُسْلِمًا بِمَعَاهِدٍ. وَقَالَ: "أَنَا أَوْلَى مَنْ وَفَى بِذِمَّتِهِ } . أَخْرَجَهُ عَبْدُ اَلرَّزَّاقِ هَكَذَا مُرْسَلًا. وَوَصَلَهُ اَلدَّارَقُطْنِيُّ, بِذِكْرِ اِبْنِ عُمَرَ فِيهِ, وَإِسْنَادُ اَلْمَوْصُولِ وَاهٍ
