Surah Al-Baqara, Verse 265
وَمَثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمُ ٱبْتِغَآءَ مَرْضَاتِ ٱللَّهِ وَتَثْبِيتًۭا مِّنْ أَنفُسِهِمْ كَمَثَلِ جَنَّةٍۭ بِرَبْوَةٍ أَصَابَهَا وَابِلٌۭ فَـَٔاتَتْ أُكُلَهَا ضِعْفَيْنِ فَإِن لَّمْ يُصِبْهَا وَابِلٌۭ فَطَلٌّۭ ۗ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ
Translation — Sahih International
And the example of those who spend their wealth seeking means to the approval of Allah and assuring [reward for] themselves is like a garden on high ground which is hit by a downpour - so it yields its fruits in double. And [even] if it is not hit by a downpour, then a drizzle [is sufficient]. And Allah, of what you do, is Seeing.
