فَأَسْرِ بِأَهْلِكَ بِقِطْعٍ مِنَ اللَّيْلِ وَاتَّبِعْ أَدْبَارَهُمْ وَلَا يَلْتَفِتْ مِنْكُمْ أَحَدٌ وَامْضُوا حَيْثُ تُؤْمَرُونَ 65
"Then travel by night with thy household, when a portion of the night (yet remains), and do thou bring up the rear: let no one amongst you look back, but pass on whither ye are ordered."
