Al Baqarah, 265 Ayah
2:265
وَمَثَلُ ٱلَّذِينَ يُنفِقُونَ أَمۡوَٰلَهُمُ ٱبۡتِغَآءَ مَرۡضَاتِ ٱللَّهِ وَتَثۡبِيتٗا مِّنۡ أَنفُسِهِمۡ كَمَثَلِ جَنَّةِۭ بِرَبۡوَةٍ أَصَابَهَا وَابِلٞ فَـَٔاتَتۡ أُكُلَهَا ضِعۡفَيۡنِ فَإِن لَّمۡ يُصِبۡهَا وَابِلٞ فَطَلّٞۗ وَٱللَّهُ بِمَا تَعۡمَلُونَ بَصِيرٌ ٢٦٥
Wa Mathalu Al-Ladhīna Yunfiqūna 'Amwālahumu Abtighā'a Marđāati Al-Lahi Wa Tathbītāan Min 'Anfusihim Kamathali Jannatin Birabwatin 'Aşābahā Wa Abilun Fa'ātat 'Ukulahā Đi`fayni Fa'in Lam Yuşibhā Wa Abilun Faţallun Wa ۗ Allāhu Bimā Ta`malūna Başīrun
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.
