THE GOLDEN CHERSONESE AND THE WAY THITHER BY ISABELLA L. BIRD (MRS. BISHOP)

And the example of those who spend their wealth seeking means to the approval of Allah and assuring [reward for] themselves is like the 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 (Surah al-Baqarah 2:265)
