Not publicizing your alms/charity giving

إِن تُبْدُوا۟ ٱلصَّدَقَٰتِ فَنِعِمَّا هِىَ ۖ وَإِن تُخْفُوهَا وَتُؤْتُوهَا ٱلْفُقَرَآءَ فَهُوَ خَيْرٌۭ لَّكُمْ ۚ وَيُكَفِّرُ عَنكُم مِّن سَيِّـَٔاتِكُمْ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌۭ

If ye disclose (acts of) charity, even so it is well, but if ye conceal them, and make them reach those (really) in need, that is best for you: It will remove from you some of your (stains of) evil. And Allah is well acquainted with what ye do.

ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُم بِٱلَّيْلِ وَٱلنَّهَارِ سِرًّۭا وَعَلَانِيَةًۭ فَلَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ

Those who (in charity) spend of their goods by night and by day, in secret and in public, have their reward with their Lord: on them shall be no fear, nor shall they grieve.

قُل لِّعِبَادِىَ ٱلَّذِينَ ءَامَنُوا۟ يُقِيمُوا۟ ٱلصَّلَوٰةَ وَيُنفِقُوا۟ مِمَّا رَزَقْنَٰهُمْ سِرًّۭا وَعَلَانِيَةًۭ مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌۭ لَّا بَيْعٌۭ فِيهِ وَلَا خِلَٰلٌ

Speak to my servants who have believed, that they may establish regular prayers, and spend (in charity) out of the sustenance we have given them, secretly and openly, before the coming of a Day in which there will be neither mutual bargaining nor befriending.

إِنَّ ٱلَّذِينَ يَتْلُونَ كِتَٰبَ ٱللَّهِ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَأَنفَقُوا۟ مِمَّا رَزَقْنَٰهُمْ سِرًّۭا وَعَلَانِيَةًۭ يَرْجُونَ تِجَٰرَةًۭ لَّن تَبُورَ

Those who rehearse the Book of Allah, establish regular Prayer, and spend (in Charity) out of what We have provided for them, secretly and openly, hope for a commerce that will never fail:
