O son of Adam! If you give your surplus it is better for you, and if you keep it, it is worse for you, but there is no harm with what is sufficient. And begin(the giving) with your dependents, and the upper hand (giving) is better than the lower hand (receiving).

If you were to rely upon Allah with the required reliance, then He would provide for you just as a bird is provided for, it goes out in the morning empty, and returns full.

There were two brothers during the time of the Messenger of Allah (s.a.w). One of them used to come to the prophet (s.a.w), and the other had some business. The businessman among them complained to the Prophet (s.a.w) about his brother, so he said:'Perhaps you are provided for because of him.'
