Go forth light and heavy (as cavalries and infantries) and strive hard in Allah’s Way with your property and your lives. This is better for you, if you know.
Had it been a near gain (booty in front of them) and an easy journey, they would have followed you, but the distance seemed too far to them. They shall swear by Allah: “If we had been able, we would surely have come forth with you”. They destroy themselves (their souls), and Allah knows that they are most surely liars.
Allah pardoned you! Why did you (not wait and) give them leave until those who are loyal had become manifest to you and you had known the liars?
Those who believe in Allah and the latter day (in reaching Allah before death) do not ask leave of you from striving hard with their property and their lives. And Allah knows the owners of piety.
Only those would ask permission of you who do not believe in Allah and the Last Day and whose hearts have doubted. So in their doubt do they waver.
And if they had wished to go forth, they would surely have made some preparation for it (war), but Allah disliked their state. So He held them back and it was said to them: Sit with those who stay behind.
Had they gone forth with you, they would have added nothing except disorder. They would have been active among you, seeking you Fitnah, and among you. There are those who would listen to them, and Allah knows the wrong-doers.
