﴿ سَيَقُولُ ٱلْمُخَلَّفُونَ إِذَا ٱنطَلَقْتُمْ إِلَىٰ مَغَانِمَ لِتَأْخُذُوهَا ذَرُونَا نَتَّبِعْكُمْ ۖ يُرِيدُونَ أَن يُبَدِّلُوا۟ كَلَٰمَ ٱللَّهِ ۚ قُل لَّن تَتَّبِعُونَا كَذَٰلِكُمْ قَالَ ٱللَّهُ مِن قَبْلُ ۖ فَسَيَقُولُونَ بَلْ تَحْسُدُونَنَا ۚ بَلْ كَانُوا۟ لَا يَفْقَهُونَ إِلَّا قَلِيلًۭا ﴾

“As soon as you [O believers] are about to set forth on a war that promises booty, those who stayed behind [aforetime] will surely say, “Allow us to go with you” - [thus showing that] they would like to alter the Word of God. Say: “By no means shall you go with us: God has declared aforetime [to whom all spoils shall belong].” Thereupon they will [surely] answer, “Nay, but you begrudge us [our share of booty]!” Nay, they can grasp but so little of the truth!”

يُرِيدُونَ أَن يُبَدِّلُواْ كَلَـمَ اللَّهِ (They want to change Allah's Words), which refers to the promise that Allah gave those who were present at Al-Hudaybiyyah, according to the explanation reported from Mujahid, Qatadah, Juwaybir and which Ibn Jarir preferred. Allah said, قُل لَّن تَتَّبِعُونَا كَذَلِكُمْ قَالَ اللَّهُ مِن قَبْلُ (Say: "You shall not follow us; thus Allah has said beforehand.") `when He promised the participants of Al-Hudaybiyyah before you asked to join them,' فَسَيَقُولُونَ بَلْ تَحْسُدُونَنَا (Then they will say: "Nay, you envy us.") `you do not want us to share the war spoils with you,' بَلْ كَانُواْ لاَ يَفْقَهُونَ إِلاَّ قَلِيلاً (Nay, but they under- stand not except a little.) the truth is nothing close to what they claimed, but they understand not.
