Al-Baqarah - 2:265

وَمَثَلُ الَّذِينَ يُنفِقُونَ أَمْوَالَهُمُ ابْتِغَاء مَرْضَاتِ اللّهِ وَتَثْبِيتًا مِّنْ أَنفُسِهِمْ كَمَثَلِ جَنَّةٍ بِرَبْوَةٍ أَصَابَهَا وَابِلٌ فَآتَتْ أُكُلَهَا ضِعْفَيْنِ فَإِن لَّمْ يُصِبْهَا وَابِلٌ فَطَلٌّ وَاللّهُ بِمَا تَعْمَلُونَ بَصِيرٌ
[2:265]
And the parable of those who spend their property to seek the pleasure of Allah and for the certainty 'of their souls is as the parable of a garden on an elevated ground, upon which heavy rain falls so it brings forth its fruit twofold but if heavy rain does not fall upon it, then light rain (is sufficient); and Allah sees what you do.
And the likeness of those who spend their substance, seeking to please Allah and to strengthen their souls, is as a garden, high and fertile: heavy rain falls on it but makes it yield a double increase of harvest, and if it receives not Heavy rain, light moisture sufficeth it. Allah seeth well whatever ye do.
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.
