ostentation and showing off

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.

لَا تَحْسَبَنَّ ٱلَّذِينَ يَفْرَحُونَ بِمَآ أَتَوا۟ وَّيُحِبُّونَ أَن يُحْمَدُوا۟ بِمَا لَمْ يَفْعَلُوا۟ فَلَا تَحْسَبَنَّهُم بِمَفَازَةٍ مِّنَ ٱلْعَذَابِ ۖ وَلَهُمْ عَذَابٌ أَلِيمٌ

And never think that those who rejoice in what they have perpetrated and like to be praised for what they did not do - never think them [to be] in safety from the punishment, and for them is a painful punishment.
