asking for it for wrong reasons
5 verses in the Holy Quran
At-Taubah 9:43
عَفَا ٱللَّهُ عَنكَ لِمَ أَذِنتَ لَهُمۡ حَتَّىٰ يَتَبَيَّنَ لَكَ ٱلَّذِينَ صَدَقُواْ وَتَعۡلَمَ ٱلۡكَٰذِبِينَ ٤٣
May Allah pardon you, [O Muhammad]; why did you give them permission [to remain behind]? [You should not have] until it was evident to you who were truthful and you knew [who were] the liars.
At-Taubah 9:45
إِنَّمَا يَسۡتَـٔۡذِنُكَ ٱلَّذِينَ لَا يُؤۡمِنُونَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَٱرۡتَابَتۡ قُلُوبُهُمۡ فَهُمۡ فِي رَيۡبِهِمۡ يَتَرَدَّدُونَ ٤٥
Only those would ask permission of you who do not believe in Allah and the Last Day and whose hearts have doubted, and they, in their doubt, are hesitating.
At-Taubah 9:49
وَمِنۡهُم مَّن يَقُولُ ٱئۡذَن لِّي وَلَا تَفۡتِنِّيٓۚ أَلَا فِي ٱلۡفِتۡنَةِ سَقَطُواْۗ وَإِنَّ جَهَنَّمَ لَمُحِيطَةُۢ بِٱلۡكَٰفِرِينَ ٤٩
And among them is he who says, "Permit me [to remain at home] and do not put me to trial." Unquestionably, into trial they have fallen. And indeed, Hell will encompass the disbelievers.
At-Taubah 9:86
وَإِذَآ أُنزِلَتۡ سُورَةٌ أَنۡ ءَامِنُواْ بِٱللَّهِ وَجَٰهِدُواْ مَعَ رَسُولِهِ ٱسۡتَـٔۡذَنَكَ أُوْلُواْ ٱلطَّوۡلِ مِنۡهُمۡ وَقَالُواْ ذَرۡنَا نَكُن مَّعَ ٱلۡقَٰعِدِينَ ٨٦
And when a surah was revealed [enjoining them] to believe in Allah and to fight with His Messenger, those of wealth among them asked your permission [to stay back] and said, "Leave us to be with them who sit [at home]."
At-Taubah 9:93
۞ إِنَّمَا ٱلسَّبِيلُ عَلَى ٱلَّذِينَ يَسۡتَـٔۡذِنُونَكَ وَهُمۡ أَغۡنِيَآءُۚ رَضُواْ بِأَن يَكُونُواْ مَعَ ٱلۡخَوَالِفِ وَطَبَعَ ٱللَّهُ عَلَىٰ قُلُوبِهِمۡ فَهُمۡ لَا يَعۡلَمُونَ ٩٣
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.
