سَيَقولُ المُخَلَّفونَ إِذَا انطَلَقتُم إِلىٰ مَغانِمَ لِتَأخُذوها ذَرونا نَتَّبِعكُم ۖ يُريدونَ أَن يُبَدِّلوا كَلامَ اللَّهِ ۚ قُل لَن تَتَّبِعونا كَذٰلِكُم قالَ اللَّهُ مِن قَبلُ ۖ فَسَيَقولونَ بَل تَحسُدونَنا ۚ بَل كانوا لا يَفقَهونَ إِلّا قَليلًا

Those who remained behind will say when you set out toward the war booty to take it, "Let us follow you." They wish to change the words of Allah. Say, "Never will you follow us. Thus did Allah say before." So they will say, "Rather, you envy us." But [in fact] they were not understanding except a little.
