[Pooya/Ali Commentary 61:2] These words here are specially directed to the faint-hearted companions who had talked much but failed miserably to back up their resolution in words with firmness in action as at the battle of Uhad. Refer to the commentary of Ali Imran: 121, 128, 140 to 142, 144, 151 to 156, 159, 166 to 168 and Anfal: 16. Those who do not put into practice what they preach are hated and disliked by Allah.
