“We were talking about how, on the Day of Badr, the Companions of the Messenger of Allah ﷺ numbered three hundred ten and something, the same number as the Companions of (Talut) who crossed the river with him, and no one crossed the river with him but a believer.”
أَنَّ أَصْحَابَ رَسُولِ اللَّهِ ﷺ كَانُوا يَوْمَ بَدْرٍ ثَلاَثَمِائَةٍ وَبِضْعَةَ عَشَرَ عَلَى عِدَّةِ أَصْحَابِ طَالُوتَ مَنْ جَازَ مَعَهُ النَّهَرَ وَمَا جَازَ مَعَهُ إِلاَّ مُؤْمِنٌ
