Musnad Ahmad

It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that once I submitted in the presence of the Messenger of Allah, "O Messenger of Allah! All the reward and merit have been taken by the wealthy people; they pray, they fast, and they also perform Hajj." The Noble Prophet (peace and blessings be upon him) said, "You also do these acts." I said, "They give charity, but we cannot give charity." The Noble Prophet (peace and blessings be upon him) said, "You can also do this: removing a bone from the path is charity, guiding someone on the way is charity, helping a weak person with your strength is charity, clarifying the speech of a person who stammers is charity, and having intercourse with your wife is also charity." I asked, "O Messenger of Allah! Do we get reward even for fulfilling our 'desire'?" The Noble Prophet (peace and blessings be upon him) said, "Tell me, if you were to do this act in a forbidden way, would you not be sinful?" I replied, "Yes." The Noble Prophet (peace and blessings be upon him) said, "You count the sin but do not count the good deed."
