The Messenger of Allah ﷺ killed a man of Banu Nadr ibn Malik at Harrah ar-Righa' at the bank of Layyat al-Bahrah. The transmitter Mahmud (ibn Khalid) also mentioned the words along with the words "at Bahrah" "the slayer and the slain were from among them". Mahmud alone transmitted in this tradition the words "at the bank of Layyah".
عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَتَلَ بِالْقَسَامَةِ رَجُلاً مِنْ بَنِي نَصْرِ بْنِ مَالِكٍ بِبَحْرَةِ الرُّغَاءِ عَلَى شَطِّ لِيَّةِ الْبَحْرَةِ قَالَ الْقَاتِلُ وَالْمَقْتُولُ مِنْهُمْ وَهَذَا لَفْظُ مَحْمُودٍ بِبَحْرَةٍ أَقَامَهُ مَحْمُودٌ وَحْدَهُ عَلَى شَطِّ لِيَّةِ الْبَحْرَةِ
