Qur'an 2:265

وَمَثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمُ ٱبْتِغَآءَ مَرْضَاتِ ٱللَّهِ وَتَثْبِيتًا مِّنْ أَنفُسِهِمْ كَمَثَلِ جَنَّةٍۭ بِرَبْوَةٍ أَصَابَهَا وَابِلٌ فَـَٔاتَتْ أُكُلَهَا ضِعْفَيْنِ فَإِن لَّمْ يُصِبْهَا وَابِلٌ فَطَلٌّ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ

And the likeness of those who spend their wealth in search of Allah's pleasure, and for the strengthening of their souls, is as the likeness of a garden on a height. The rainstorm smiteth it and it bringeth forth its fruit twofold. And if the rainstorm smite it not, then the shower. Allah is Seer of what ye do.
