Surah Al-Baqarah · Ayah 265

وَمَثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمُ ٱبْتِغَآءَ مَرْضَاتِ ٱللَّهِ وَتَثْبِيتًۭا مِّنْ أَنفُسِهِمْ كَمَثَلِ جَنَّةٍۭ بِرَبْوَةٍ أَصَابَهَا وَابِلٌۭ فَـَٔاتَتْ أُكُلَهَا ضِعْفَيْنِ فَإِن لَّمْ يُصِبْهَا وَابِلٌۭ فَطَلٌّۭ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ

Wa masalul lazeena yunfiqoona amwaalahumub ti ghaaaa'a mardaatil laahi wa tasbeetam min anfusihim kamasali jannatim birabwatin asaabahaa waabilun fa aatat ukulahaa di'faini fa il lam yusibhaa waabilun fatall; wallaahu bimaa ta'maloona Baseer

And the example of those who spend their wealth seeking means to the approval of Allah and assuring [reward for] themselves is like a garden on high ground which is hit by a downpour - so it yields its fruits in double. And [even] if it is not hit by a downpour, then a drizzle [is sufficient]. And Allah, of what you do, is Seeing.
