From Quran
وَمَا تُنفِقُوا۟ مِنۡ خَیۡرࣲ فَلِأَنفُسِكُمۡۚ وَمَا تُنفِقُونَ إِلَّا ٱبۡتِغَاۤءَ وَجۡهِ ٱللَّهِۚ وَمَا تُنفِقُوا۟ مِنۡ خَیۡرࣲ یُوَفَّ إِلَیۡكُمۡ وَأَنتُمۡ لَا تُظۡلَمُونَ
سورة البقرة : ٢٨٢
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.
Surah Al-Baqarah: 272

عن أبي هريرة رضي الله عنه أن رسول الله صلى الله عليه وسلم قال:
ما نقصت صدقة من مال، وما زاد الله عبداً بعفو إلا عزاً، وما تواضع أحد لله إلا رفعه الله عز وجل
رواه مسلم، ٢٥٨٨
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said,
Wealth is not diminished by giving (in charity). Allah augments the honour of one who forgives; and one who displays humbleness towards another seeking the pleasure of Allah, Allah exalts him in ranks.
Narrated by Muslim, 2588
