Salaam and Greetings of Peace:
Abu Dharr reported that some of his Companions said: “O Messenger of Allah, the rich have taken away all the rewards. They observe the prayer as we do, and they keep the fasts as we do, and they give sadaqah (charity) from their surplus riches.”
Upon this he (the Prophet) said: “Has Allah not prescribed for you (a course) by following which you can also do sadaqah? Verily in every tasbih (i.e. saying Subhanallah) there is a sadaqah, every takbir (i.e. saying Allahu Akbar) is a sadaqah, every tahmid (i.e. saying Alhamdulillah) is a sadaqah, every tahlil (i.e. saying Lailaha illallah) is a sadaqah, enjoining of good is a sadaqah, forbidding of evil is a sadaqah,
“Doing justice between two people is sadaqah; assisting a man, or lifting up his belongings is sadaqah; a good word is sadaqah; every step you take towards prayer is sadaqah; and removing harmful things from the path is sadaqah.”
- Hadiths of the Prophet (pbuh)
Alhamdulillah, that both rich and poor can give in charity. Indeed, every good intention toward God and every act of kindness toward your fellow human beings is an act of charity, a giving of yourself.
