Abu Dharr (May Allah be pleased with him) reported

The Messenger of Allah (ﷺ) said, "Every morning charity is due from every joint bone of the body of every one of you. Every utterance of Allah's Glorification (i.e., Subhan-Allah) is an act of charity, and every utterance of praise of Him (i.e., Al-hamdu lillah) is an act of charity, and every utterance of profession of Faith (i.e., La ilaha illallah) is an act of charity, and every utterance of His Greatness (i.e., Allahu Akbar) is an act of charity; and enjoining good is an act of charity and forbidding what is disreputable is an act of charity; and two Rak'ah prayer which one offers in the forenoon (Ad- Duha) will suffice for all this."
