Sura al-Baqara 2:265

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

wa-mathalu lladhīna yunfiqūna amwālahumu ibtighāʾa marḍāti allāhi wa-tathbītan min anfusihim ka-mathali jannatin bi-rabwatin aṣābahā wābilun fa-ātat ukulahā ḍiʿfayni fa-in lam yuṣibhā wābilun fa-ṭallun wallāhu bi-mā taʿmalūna baṣīrun

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.
