Translation:

73. But if good fortune comes to you from Allah they would be sure to say as if there had never been ties of affection between you and them "Oh! I wish I had been with them; a fine thing should I then have made of it!"

Notes (Tafseer)

590. Just a selfish man's thought. Such men are far from being a source of strength to their community. They are no use in a fight, and the next verse by implication discards them.
