3:180 وَلَا يَحْسَبَنَّ ٱلَّذِينَ يَبْخَلُونَ بِمَآ ءَاتَىٰهُمُ ٱللَّهُ مِن فَضْلِهِۦ هُوَ خَيْرًا لَّهُم بَلْ هُوَ شَرٌّ لَّهُمْ سَيُطَوَّقُونَ مَا بَخِلُوا۟ بِهِۦ يَوْمَ ٱلْقِيَٰمَةِ وَلِلَّهِ مِيرَٰثُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ
And let not those deem, who are niggardly in giving away that which Allah has granted them out of His grace, that it is good for them; nay, it is worse for them; they shall have that whereof they were niggardly made to cleave to their necks on the resurrection day; and Allah's is the heritage of the heavens and the earth; and Allah is aware of what you do.
4:37 ٱلَّذِينَ يَبْخَلُونَ وَيَأْمُرُونَ ٱلنَّاسَ بِٱلْبُخْلِ وَيَكْتُمُونَ مَآ ءَاتَىٰهُمُ ٱللَّهُ مِن فَضْلِهِۦ وَأَعْتَدْنَا لِلْكَٰفِرِينَ عَذَابًا مُّهِينًا
Those who are niggardly and bid people to be niggardly and hide what Allah has given them out of His grace; and We have prepared for the unbelievers a disgraceful chastisement.
But when He gave them out of His grace, they became niggardly of it and they turned back and they withdrew.
If He should ask you for it and urge you, you will be niggardly, and He will bring forth your malice.
47:38 هَٰٓأَنتُمْ هَٰٓؤُلَآءِ تُدْعَوْنَ لِتُنفِقُوا۟ فِى سَبِيلِ ٱللَّهِ فَمِنكُم مَّن يَبْخَلُ وَمَن يَبْخَلْ فَإِنَّمَا يَبْخَلُ عَن نَّفْسِهِۦ وَٱللَّهُ ٱلْغَنِىُّ وَأَنتُمُ ٱلْفُقَرَآءُ وَإِن تَتَوَلَّوْا۟ يَسْتَبْدِلْ قَوْمًا غَيْرَكُمْ ثُمَّ لَا يَكُونُوٓا۟ أَمْثَٰلَكُم
Behold! you are those who are called upon to spend in Allah's way, but among you are those who are niggardly, and whoever is niggardly is niggardly against his own soul; and Allah is Self-sufficient and you have need (of Him), and if you turn back He will bring in your place another people, then they will not be like you.
57:24 ٱلَّذِينَ يَبْخَلُونَ وَيَأْمُرُونَ ٱلنَّاسَ بِٱلْبُخْلِ وَمَن يَتَوَلَّ فَإِنَّ ٱللَّهَ هُوَ ٱلْغَنِىُّ ٱلْحَمِيدُ
