2. Al-Baqara (The Cow)

Surah: 2   Aya: 265

265. Wamathalu allatheena yunfiqoona amwalahumu ibtighaa mardati Allahi watathbeetan min anfusihim kamathali jannatin birabwatin asabaha wabilun faatat okulaha diAAfayni fa-in lam yusibha wabilun fatallun waAllahu bima taAAmaloona baseerun
  

  Translation

265. And the likeness of those who spend their wealth seeking Allâh's Pleasure while they in their ownselves are sure and certain that Allâh will reward them (for their spending in His Cause), is the likeness of a garden on a height; heavy rain falls on it and it doubles its yield of harvest. And if it does not receive heavy rain, light rain suffices it. And Allâh is All-Seer of (knows well) what you do.
