Charity does not decrease wealth

You want respect, learn to forgive people for the Sake of Allaah. You want high ranks, learn to be humble for the Sake of Allaah. Do not be a miser. Charity does not decrease wealth.

Abu Huraira reported Allah's Messenger (sallallaahu alayhi wa sallam) as saying:

Charity does not in any way decrease the wealth and the servant who forgives Allah adds to his respect, and the one who shows humility Allah elevates him.

[Sahih Muslim Hadiith No. 2588]

As for the part of the hadiith which reads "the one who shows humility Allaah elevates him," al-Qaadii 'iyaaD says that there are two ways to look at it:

First, he shows humility for Allaah and Allaah elevates his rank in this world as a recompense for the humility he showed for His Sake. That elevation creates in the hearts [of people] love, a lofty place, and rank for the person.

Second, it refers to the reward he will get in the next world or showing humility for His Sake.
