﴿ لَوْ كَانَ عَرَضًۭا قَرِيبًۭا وَسَفَرًۭا قَاصِدًۭا لَّٱتَّبَعُوكَ وَلَٰكِنۢ بَعُدَتْ عَلَيْهِمُ ٱلشُّقَّةُ ۚ وَسَيَحْلِفُونَ بِٱللَّهِ لَوِ ٱسْتَطَعْنَا لَخَرَجْنَا مَعَكُمْ يُهْلِكُونَ أَنفُسَهُمْ وَٱللَّهُ يَعْلَمُ إِنَّهُمْ لَكَٰذِبُونَ ﴾

“Had there been [a prospect of] immediate gain, and an easy journey, they would certainly have followed thee, [O Prophet:] but the distance was too great for them. And yet, [after your return, O believers,] they will swear by God, "Had we been able to do so, we would certainly have set out with you!" - [and by thus falsely swearing] they will be destroying their own selves: for God knows indeed that they are lying!”

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.
