153. " (remember) when you were climbing (the hillside) and paid no heed to
any one, while the messenger was calling you from your rear,
so he inflicted you with grief on grief that you might not be sorry for what
escaped you and neither for what befell you;
and allah is well aware of what you do."

commentary:
in this verse the qur'an reminds muslims the ending scene of the
battle of 'uh¤ud and tells them to remember when they were scattered and
they were running away without paying any attention to their fellow strivers
at their backs to see in what condition they were, though the prophet
(p.b.u.h.) was calling them from their behind.

"(remember) when you were climbing (the hillside) and paid no heed to any
one, while the messenger was calling you from your rear, ..."

the prophet (p.b.u.h.) was calling them, saying: " o' servants of allah!
return to me! return to me! i am the messenger of allah."

it tells them that at that time neither of them attended to his words:

"... so he inflicted you with grief on grief...."

the invasion of grief and sorrow to them was for that they would not
be sorry any more for losing the spoils of war, and that they would not be
worried about the wounds they suffered in the battlefield in the path of
victory; and surely allah knows what they do.

"... that you might not be sorry for what escaped you and neither for what
befell you; and allah is well aware of what you do."
