spending for the sake of Allah

{ Do they not know that it is Allāh who accepts repentance from His servants and receives charities and that it is Allāh who is the Accepting of Repentance,1 the Merciful? }

{ And the example of those who spend their wealth seeking means to the approval of Allāh 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 Allāh, of what you do, is Seeing. }
