Surah Al-Baqarah (The Cow), Verse 265

وَمَثَلُ الَّذِیْنَ یُنْفِقُوْنَ اَمْوَالَهُمُ ابْتِغَآءَ مَرْضَاتِ اللّٰهِ وَتَثْبِیْتًا مِّنْ اَنْفُسِهِمْ كَمَثَلِ جَنَّةٍ بِرَبْوَةٍ اَصَابَهَا وَابِلٌ فَاٰتَتْ اُكُلَهَا ضِعْفَیْنِ فَاِنْ لَّمْ یُصِبْهَا وَابِلٌ فَطَلٌّ وَاللّٰهُ بِمَا تَعْمَلُوْنَ بَصِیْرٌ ۟

Wa masalul lazeena yunfiqoona amwaalahu mubtighaaa'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 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.”
