فَأَسْرِ بِأَهْلِكَ بِقِطْعٍ مِّنَ اللَّيْلِ وَاتَّبِعْ أَدْبَارَهُمْ وَلاَ يَلْتَفِتْ مِنكُمْ أَحَدٌ وَامْضُواْ حَيْثُ تُؤْمَرُونَ
[15:65]
Therefore go forth with your followers in a part of the night and yourself follow their rear, and let not any one of you turn round, and go forth whither you are commanded.
"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."
So travel with thy household in a portion of the night, and follow thou their backs. Let none of you turn round, but go whither ye are commanded.
