Read and reflect on verse 272 from Surah Al-Baqara: And the parable of those who spend their possessions out of a longing to please God, and out of their own inner certainty, is that of a garden on high...
وَمَثَلُ الَّذِينَ يُنْفِقُونَ أَمْوَالَهُمُ ابْتِغَاءَ مَرْضَاتِ اللَّهِ وَتَثْبِيتًا مِنْ أَنْفُسِهِمْ كَمَثَلِ جَنَّةٍ بِرَبْوَةٍ أَصَابَهَا وَابِلٌ فَآتَتْ أُكُلَهَا ضِعْفَيْنِ فَإِنْ لَمْ يُصِبْهَا وَابِلٌ فَطَلٌّ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ
And the parable of those who spend their possessions out of a longing to please God, and out of their own inner certainty, is that of a garden on high, fertile ground: a rainstorm smites it, and thereupon it brings forth its fruit twofold; and if no rainstorm smites it, soft rain [falls upon it]. And God sees all that you do.
