Translation:

72. There are certainly among you men who would tarry behind: if a misfortune befalls you, They say: "Allah did favor us in that we were not present among them."

Notes (Tafseer)

589. The doubter detaches himself in thought and action from the community. If the general body has a reverse, he blesses Allah that he was not among them, instead of being ashamed of himself for desertion. If the general body wins a success, he does not rejoice for the common cause, but only regrets for himself that he was not there to share in the glory and the gains!
