Ibn Kathir (Abridged)
Hafiz Ibn Kathirيُرِيدُونَ 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.
