AT TAUBAH — Ayat 93

إِنَّمَا السَّبِيلُ عَلَى الَّذِينَ يَسْتَأْذِنُونَكَ وَهُمْ أَغْنِيَاء رَضُواْ بِأَن يَكُونُواْ مَعَ الْخَوَالِفِ وَطَبَعَ اللّهُ عَلَى قُلُوبِهِمْ فَهُمْ لاَ يَعْلَمُونَ

The cause [for blame] is only upon those who ask permission of you while they are rich. They are satisfied to be with those who stay behind, and Allah has sealed over their hearts, so they do not know.
