"We used to say that the participants of Badr on the Day of Badr were like the number of companions of Talut, three hundred and thirteen men." [He said:] There is something on this topic from Ibn 'Abbas.  

أَنَّ أَصْحَابَ بَدْرٍ يَوْمَ بَدْرٍ كَعِدَّةِ أَصْحَابِ طَالُوتَ ثَلاَثِمِائَةٍ وَثَلاَثَةَ عَشَرَ رَجُلاً قَالَ وَفِي الْبَابِ عَنِ ابْنِ عَبَّاسٍ
