At-Tawba 9:42

If it had been an easy win within reach and a short journey, those [hypocrites] would have followed you, but the distance seemed too far for them. They will swear by Allah[43], “If we had been able, we would have surely joined you,” destroying themselves [through false oaths], and Allah knows that they are liars.

[43] When you return from the Tabūk expedition in which the hypocrites did not participate.

Had it been a near [i.e., easy] gain and a moderate trip, they [i.e., the hypocrites] would have followed you, but distant to them was the journey. And they will swear by Allāh,[481] "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allāh knows that indeed they are liars.

[481] When you return from the Tabūk expedition.

42. Had it been a near gain (booty in front of them) and an easy journey, they would have followed you, but the distance (Tabuk expedition) was long for them; and they would swear by Allâh, "If we only could, we would certainly have come forth with you." They destroy their ownselves, and Allâh knows that they are liars.

Had it been a near adventure and an easy journey they had followed thee, but the distance seemed too far for them. Yet will they swear by Allah (saying): If we had been able we would surely have set out with you. They destroy their souls, and Allah knoweth that they verily are liars.
