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.
