Read Ruku 38 of the Quran

وَمَآ أَنفَقْتُم مِّن نَّفَقَةٍ أَوْ نَذَرْتُم مِّن نَّذْرٍۢ فَإِنَّ ٱللَّهَ يَعْلَمُهُۥ ۗ وَمَا لِلظَّـٰلِمِينَ مِنْ أَنصَارٍ ﴿٢٧٠﴾

And whatever you spend of expenditures or make of vows - indeed, Allah knows of it. And for the wrongdoers there are no helpers.

إِن تُبْدُوا۟ ٱلصَّدَقَـٰتِ فَنِعِمَّا هِىَ ۖ وَإِن تُخْفُوهَا وَتُؤْتُوهَا ٱلْفُقَرَآءَ فَهُوَ خَيْرٌۭ لَّكُمْ ۚ وَيُكَفِّرُ عَنكُم مِّن سَيِّـَٔاتِكُمْ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌۭ ﴿٢٧١﴾

If you disclose your charitable expenditures, they are good; but if you conceal them and give them to the poor, it is better for you, and He will remove from you some of your misdeeds [thereby]. And Allah, with what you do, is [fully] Acquainted.

۞ لَّيْسَ عَلَيْكَ هُدَىٰهُمْ وَلَـٰكِنَّ ٱللَّهَ يَهْدِى مَن يَشَآءُ ۗ وَمَا تُنفِقُوا۟ مِنْ خَيْرٍۢ فَلِأَنفُسِكُمْ ۚ وَمَا تُنفِقُونَ إِلَّا ٱبْتِغَآءَ وَجْهِ ٱللَّهِ ۚ وَمَا تُنفِقُوا۟ مِنْ خَيْرٍۢ يُوَفَّ إِلَيْكُمْ وَأَنتُمْ لَا تُظْلَمُونَ ﴿٢٧٢﴾

Not upon you, [O Muhammad], is [responsibility for] their guidance, but Allah guides whom He wills. And whatever good you [believers] spend is for yourselves, and you do not spend except seeking the countenance of Allah. And whatever you spend of good - it will be fully repaid to you, and you will not be wronged.

لِلْفُقَرَآءِ ٱلَّذِينَ أُحْصِرُوا۟ فِى سَبِيلِ ٱللَّهِ لَا يَسْتَطِيعُونَ ضَرْبًۭا فِى ٱلْأَرْضِ يَحْسَبُهُمُ ٱلْجَاهِلُ أَغْنِيَآءَ مِنَ ٱلتَّعَفُّفِ تَعْرِفُهُم بِسِيمَـٰهُمْ لَا يَسْـَٔلُونَ ٱلنَّاسَ إِلْحَافًۭا ۗ وَمَا تُنفِقُوا۟ مِنْ خَيْرٍۢ فَإِنَّ ٱللَّهَ بِهِۦ عَلِيمٌ ﴿٢٧٣﴾

[Charity is] for the poor who have been restricted for the cause of Allah, unable to move about in the land. An ignorant [person] would think them self-sufficient because of their restraint, but you will know them by their [characteristic] sign. They do not ask people persistently [or at all]. And whatever you spend of good - indeed, Allah is Knowing of it.
