What should I do to be rich and have money in order to serve with great morals?

You don't need to be wealthy in order to help and serve others. Charity or sadaqa as it is traditionally understood comprises donating money or goods to help the poor. According to this understanding, this is quite a narrow perspective. The Arabic word tasaddaqa (to give charity) is derived from the word “sadaqa” which means tell the truth or be sincere. Sadaqa is giving with sincerity so every act of giving can be a sadaqa. The companion Abu Dharr (ra) reported the Prophet (saw) said: “There is no person who does not have the obligation of (doing) charity every day that the sun rises.” He was asked, “O Messenger of Allah, from where would we get something to give in charity (so often)?” To which he replied, “Indeed the gates to goodness are many: glorifying God, praising Him, magnifying Him, saying ‘There is no god but Allah,’ enjoining the good and forbidding the wrong, removing (any source of) harm from the road, making the deaf hear (and understand), guiding the blind, showing the seeker his need, striving as far as your two legs could carry you and with deep concern to give succor to him who asks, carrying with the strength of your arms (the burdens of) the weak. All these are (acts of) charity.” And he added, “And your smiling in the face of your brother is charity, your removing of stones, thorns, and bones from people’s paths is charity, and your guiding a man gone astray in the world is charity for you.” (Tirmidhi 1970) This is the essence of charity.
