the messenger of god left his house and the quraysh were lying on their backs. this means that they fell dead in front of him. the arabs also say lij bifulan meaning labt bih which means laj or labt.
فخرج رسول الله من منزله وقريش ملبوط بهم. يعني أنهم سقطوا صرعى بين يديه، وتقول العرب أيضا ليج بفلان، يعني لبط به، وهو الليج واللبط.
