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
Those who were left behind will say, when ye set forth to capture booty: Let us go with you. They fain would change the verdict of Allah. Say (unto them, O Muhammad): Ye shall not go with us. Thus hath Allah said beforehand. Then they will say: Ye are envious of us. Nay, but they understand not, save a little.
Surah Al-Fath(48:15)
