۞ إِنَّمَا ٱلسَّبِيلُ عَلَى ٱلَّذِينَ يَسْتَـْٔذِنُونَكَ وَهُمْ أَغْنِيَآءُ ۚ رَضُوا۟ بِأَن يَكُونُوا۟ مَعَ ٱلْخَوَالِفِ وَطَبَعَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ فَهُمْ لَا يَعْلَمُونَ
The road (of blame) is only against those who ask for leave of thee (to stay at home) when they are rich. They are content to be with the useless. Allah hath sealed their hearts so that they know not.
Surah At-Tawba(9:93)
