لَن تَنَالُوا۟ ٱلْبِرَّ حَتَّىٰ تُنفِقُوا۟ مِمَّا تُحِبُّونَ ۚ وَمَا تُنفِقُوا۟ مِن شَىْءٍۢ فَإِنَّ ٱللَّهَ بِهِۦ عَلِيمٌۭ

"You will never attain true righteousness until you spend out of what you hold dear; and whatever you spend, indeed Allah knows it well."

(Surah Ali Imran, 3:92)

مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ فِى سَبِيلِ ٱللَّهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتْ سَبْعَ سَنَابِلَ فِى كُلِّ سُنۢبُلَةٍۢ مِّا۟ئَةُ حَبَّةٍۢ ۗ وَٱللَّهُ يُضَـٰعِفُ لِمَن يَشَآءُ ۗ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ

"The example of those who spend their wealth in the way of Allah is like a seed that grows producing seven ears, each ear containing a hundred grains. And Allah multiplies reward for whom He wills, and Allah is All-Encompassing (in His mercy) and All-Knowing."

(Surah Al-Baqarah, 2:261)

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَنفِقُوا۟ مِن طَيِّبَـٰتِ مَا كَسَبْتُمْ وَمِمَّآ أَخْرَجْنَا لَكُم مِّنَ ٱلْأَرْضِ ۖ وَلَا تَيَمَّمُوا۟ ٱلْخَبِيثَ مِنْهُ تُنفِقُونَ وَلَسْتُم بِـَٔاخِذِيهِ إِلَّآ أَن تُغْمِضُوا۟ فِيهِ ۚ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ غَنِىٌّ حَمِيدٌ

"O you who believe! Spend (in the way of Allah) from the good things you have earned and from what We have brought forth from the earth for you. And do not deliberately choose the bad thereof (to give as charity or zakat), while you yourselves would not take it except with closed eyes (i.e., if it were given to you). And know that Allah is Self-Sufficient, Praiseworthy."

(Surah Al-Baqarah, 2:267)

"When a child of Adam dies, all his deeds come to an end except for three: ongoing charity (waqf), beneficial knowledge, and a righteous child who prays for him."

(Narrated by Muslim)
