It was narrated from Abu Dharr that some people from among the companions of the Prophet (peace and blessings of Allaah be upon him) said to the Prophet (peace and blessings of Allaah be upon him): “O Messenger of Allaah, the rich people will get more reward. They pray as we pray, and they fast as we fast, but they give in charity from their excess wealth.” He said, “Has not Allaah given you things with which you can give charity? Every tasbeehah (saying ‘Subhaan Allaah (Glory be to Allaah)’) is a charity. Every Takbeerah (saying ‘Allaahu akbar (Allaah is Most Great)’) is a charity. Every Tahmeedah (saying ‘al-hamdu-Lillaah (praise be to Allaah)’ is a charity. Every Tahleelah (saying ‘Laa ilaaha ill-Allaah (there is no god but Allaah)’) is a charity. Enjoining what is good is a charity. Forbidding what is evil is a charity. Having intercourse (with one’s wife) is a charity.” They said, “O Messenger of Allaah, if one of us fulfils his desire, is there reward in that?” He said, “Do you not see that if he does it in a haraam way he will have the burden of sin? So if he does it in a halaal way, he will have a reward for that.”
(Narrated by Muslim, 1674)
