In Islam, the Opportunity to Do Good is Everywhere

"When one of you plants a tree, the fruits of which all creatures enjoy, let it be written as charity."

- Prophet Muhammad (SAW), as reported by Anas bin Malik

Don't ever underestimate the power of the small act of kindness... Allah sees everything...

Practice

Practice what you have learned, for theory without practice is like a spirit without a body. One who is content with learning alone is not learned, for the truly learned seeks more than mere words. Divine guidance entails self-mortification, without which contemplation is unattainable.

- Al-Hujwiri, "The Kashf al-Mahjub"
