recall when you were fleeing without casting even a side glance at anyone and the messenger was calling out to you from the rear. then allah requited you by inflicting grief after grief upon you so as to instruct you neither to grieve for the losses you might suffer nor for the afflictions that might befall you. allah knows all that you do.
إذ تصعدون ولا تلوون على أحد والرسول يدعوكم في أخراكم فأثابكم غما بغم لكيلا تحزنوا على ما فاتكم ولا ما أصابكم والله خبير بما تعملون
