Holy Qur’an 48:16

Those who had managed to be left behind will say, when you go forth to the spoils that you may get them, ‘Let us follow you.’ They seek to change the decree of Allah. Say, ‘You shall not follow us. Thus has Allah said beforehand.’ Then they will say, ‘Nay, but you envy us.’ Not so, but they understand not except a little.
