About the Surah

       If it was a situation where gain (of booty) was quick and the journey was easy, then they (the hypocrites) would have followed you but the journey (of Tabuk expedition) appeared to them (the hypocrites) too far and tiresome (hence, they were left behind). (And when you return) they would swear by Allah: “If it was possible for us, we would have accompanied you.” They destroy their own selves, and Allah knows that they are definitely liars.
