Mealler

When a sura is revealed, stating: "Believe in GOD, and strive with His messenger," even the strong among them say, "Let us stay behind!"

They chose to be with the sedentary. Consequently, their hearts were sealed, and thus, they cannot comprehend.

As for the messenger and those who believed with him, they eagerly strive with their money and their lives. These have deserved all the good things; they are the winners.

GOD has prepared for them gardens with flowing streams, wherein they abide forever. This is the greatest triumph.

The Arabs made up excuses, and came to you seeking permission to stay behind. This is indicative of their rejection of GOD and His messenger - they stay behind. Indeed, those who disbelieve among them have incurred a painful retribution.
