The number of the warriors of Badr
Sahih Bukhari
حَدَّثَنَا عَمْرُو بْنُ خَالِدٍ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا أَبُو إِسْحَاقَ، قَالَ سَمِعْتُ الْبَرَاءَ ـ رضى الله عنه ـ يَقُولُ حَدَّثَنِي أَصْحَابُ، مُحَمَّدٍ صلى الله عليه وسلم مِمَّنْ شَهِدَ بَدْرًا أَنَّهُمْ كَانُوا عِدَّةَ أَصْحَابِ طَالُوتَ الَّذِينَ جَازُوا مَعَهُ النَّهَرَ، بِضْعَةَ عَشَرَ وَثَلاَثَمِائَةٍ. قَالَ الْبَرَاءُ لاَ وَاللَّهِ مَا جَاوَزَ مَعَهُ النَّهَرَ إِلاَّ مُؤْمِنٌ.
Narrated Al-Bara: The companions of (the Prophet) Muhammad who took part in Badr, told me that their number was that of Saul's (i.e. Talut's) companions who crossed the river (of Jordan) with him and they were over three-hundred-and-ten men. By Allah, none crossed the river with him but a believer. (See Qur'an 2:249)
