You just escort your family, they said, and take them out of this town at the dead hours of the night hanging on their rear and none of you shall look in the direction from which you are going and keep going to where you are commanded

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

So set out with your family during a portion of the night meaning

*37) That is, "You should walk behind your people lest anyone of them should stay behind" .
*38) It did not mean: "look not behind thee... .lest thou be consumed. . . "as stated in the Bible. But it merely meant to warn them: "None of you should turn round to see what was happening behind them lest you should stop to see the fun, when you heard the cries of the smitten people. For it is neither the time of enjoying "fun", nor of shedding tears of regret. If you stop even for a minute in the territory of the smitten people you also might get hurt from the rain of stones."
