[Machine] Khalid bin Saeed, Aban bin Saeed, and Amr bin Saeed were among the early Muslims who participated in battles. Uhayhah and Al-Aas, the sons of Saeed bin Al-Aas, were killed in the Battle of Badr as disbelievers. They were all killed by Ali bin Abi Talib, as I mentioned when I talked about Khalid bin Saeed.
«كَانَ خَالِدُ بْنُ سَعِيدٍ وَأَبَانُ بْنُ سَعِيدٍ وَعَمْرُو بْنُ سَعِيدٍ مِنْ أَهْلِ السَّوَابِقِ فِي الْإِسْلَامِ وَأُحَيْحَةُ وَالْعَاصُ ابْنَا سَعِيدِ بْنِ الْعَاصِ قُتِلَا يَوْمَ بَدْرٍ كَافِرِينَ وَإِنَّمَا قَتَلَهُمَا جَمِيعًا عَلِيُّ بْنُ أَبِي طَالِبٍ لَمَّا ذَكَرْتُهُ فِي ذِكْرِ خَالِدِ بْنِ سَعِيدٍ
