يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَنفِقُوا۟ مِمَّا رَزَقْنَـٰكُم مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌ لَّا بَيْعٌ فِيهِ وَلَا خُلَّةٌ وَلَا شَفَـٰعَةٌ ۗ وَٱلْكَـٰفِرُونَ هُمُ ٱلظَّـٰلِمُونَ

O you who have believed, spend from that which We have provided for you before there comes a Day in which there is no exchange [i.e., ransom] and no friendship and no intercession. And the disbelievers - they are the wrongdoers.

البقرة 254

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تُبْطِلُوا۟ صَدَقَـٰتِكُم بِٱلْمَنِّ وَٱلْأَذَىٰ كَٱلَّذِى يُنفِقُ مَالَهُۥ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۖ فَمَثَلُهُۥ كَمَثَلِ صَفْوَانٍ عَلَيْهِ تُرَابٌ فَأَصَابَهُۥ وَابِلٌ فَتَرَكَهُۥ صَلْدًا ۖ لَّا يَقْدِرُونَ عَلَىٰ شَىْءٍ مِّمَّا كَسَبُوا۟ ۗ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَـٰفِرِينَ

O you who have believed, do not invalidate your charities with reminders [of it] or injury as does one who spends his wealth [only] to be seen by the people and does not believe in Allāh and the Last Day. His example is like that of a [large] smooth stone upon which is dust and is hit by a downpour that leaves it bare. They are unable [to keep] anything of what they have earned. And Allāh does not guide the disbelieving people.

البقرة 264

مَثَلُ مَا يُنفِقُونَ فِى هَـٰذِهِ ٱلْحَيَوٰةِ ٱلدُّنْيَا كَمَثَلِ رِيحٍ فِيهَا صِرٌّ أَصَابَتْ حَرْثَ قَوْمٍ ظَلَمُوٓا۟ أَنفُسَهُمْ فَأَهْلَكَتْهُ ۚ وَمَا ظَلَمَهُمُ ٱللَّهُ وَلَـٰكِنْ أَنفُسَهُمْ يَظْلِمُونَ

The example of what they spend in this worldly life is like that of a wind containing frost which strikes the harvest of a people who have wronged themselves [i.e., sinned] and destroys it. And Allāh has not wronged them, but they wrong themselves.

آل عمران 117

إِنَّ ٱلَّذِينَ كَفَرُوا۟ وَمَاتُوا۟ وَهُمْ كُفَّارٌ فَلَن يُقْبَلَ مِنْ أَحَدِهِم مِّلْءُ ٱلْأَرْضِ ذَهَبًا وَلَوِ ٱفْتَدَىٰ بِهِۦٓ ۗ أُو۟لَـٰٓئِكَ لَهُمْ عَذَابٌ أَلِيمٌ وَمَا لَهُم مِّن نَّـٰصِرِينَ

Indeed, those who disbelieve and die while they are disbelievers - never would the [whole] capacity of the earth in gold be accepted from one of them if he would [seek to] ransom himself with it. For those there will be a painful punishment, and they will have no helpers.

آل عمران 91

وَٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ رِئَآءَ ٱلنَّاسِ وَلَا يُؤْمِنُونَ بِٱللَّهِ وَلَا بِٱلْيَوْمِ ٱلْـَٔاخِرِ ۗ وَمَن يَكُنِ ٱلشَّيْطَـٰنُ لَهُۥ قَرِينًا فَسَآءَ قَرِينًا

And [also] those who spend of their wealth to be seen by the people and believe not in Allāh nor in the Last Day. And he to whom Satan is a companion - then evil is he as a companion.
