This is just as the Messenger of Allah used to perform raids in the early morning. He would wait to see if he heard the Adhan (call to prayer) from the people. If he heard it he would leave them alone, and if he didn't hear it he would attack.

Then Allah says,

فَأَثَرْنَ بِهِ نَقْعًا

En route to launch an attack on Allah's enemies at dawn
