If there had been immediate gain (in sight), and the journey easy, they would (all) without doubt have followed thee, but the distance was long, (and weighed) on them. They would indeed swear by Allah, "If we only could, we should certainly have come out with you": They would destroy their own souls; for Allah doth know that they are certainly lying. (42)
Tafsir
A hypocrite is one who remains to the fore in the profitable and undemanding aspects of Islam, but who recoils when he feels that his interests are being affected. On such occasions, what such weaklings rely on is excuses. They try to hide their inaction by attractive explanations. In view of collective considerations, if the chief of believers accepts their excuses, they are very happy, thinking that they have successfully hidden their reluctance behind a veil of words. But they forget that their real dealings are not with a human being but with God, and He very well knows the truth about every man. God sometimes reveals the hidden aspects of such persons in this world, but in the Hereafter the truth about everyone is going to be laid bare.
