At-Tawbah 9:74
يَحْلِفُونَ بِاللَّهِ مَا قَالُوا وَلَقَدْ قَالُوا كَلِمَةَ الْكُفْرِ وَكَفَرُوا بَعْدَ إِسْلَامِهِمْ وَهَمُّوا بِمَا لَمْ يَنَالُوا ۚ وَمَا نَقَمُوا إِلَّا أَنْ أَغْنَاهُمُ اللَّهُ وَرَسُولُهُ مِن فَضْلِهِ ۚ فَإِن يَتُوبُوا يَكُ خَيْرًا لَّهُمْ ۖ وَإِن يَتَوَلَّوْا يُعَذِّبْهُمُ اللَّهُ عَذَابًا أَلِيمًا فِي الدُّنْيَا وَالْآخِرَةِ ۚ وَمَا لَهُمْ فِي الْأَرْضِ مِن وَلِيٍّ وَلَا نَصِيرٍ ٧٤

They swear by God that they said nothing, but they indeed said the word of unbelief and disbelieved, after they had surrendered. They purposed what they never attained to, and they took revenge only that God enriched them, and His Messenger, of His bounty. So if they repent it will be better for them; if they turn away, God will chastise them with a painful chastisement in this world and the next; on the earth they have no protector or helper. (9:74)
