Fal mugheeraati subha

*3) The practice among the Arabs was that when they had to mount a raid on a settlement, they marched out in the night so as to take the enemy by surprise; then they would launch a sudden attack early. in the morning so that everything became visible in the light of day, and at the same tune it did not become so bright that the victim could notice their movement from a distance and be ready to meet the offensive.
