Sayyiduna Abu Dharr (may Allah be pleased with him) says: I repeated this statement of the Prophet (peace and blessings be upon him) that it is obligatory for every person to give charity on himself every day. Then I said: O Messenger of Allah! How can I give charity, when we do not possess any wealth? The Prophet (peace and blessings be upon him) said: Saying "Allahu Akbar", "Subhanallah", "Alhamdulillah", "La ilaha illallah", and "Astaghfirullah" is also charity. Enjoining good and forbidding evil is also charity. Removing thorns, bones, stones, etc. from people's path, guiding a blind person, making a mute or deaf person understand something, if you have knowledge, guiding someone who seeks guidance for a need, running quickly to help a distressed person who calls for help, and giving full support to the weak—these are all acts of charity from you for yourself. In fact, even having intercourse with your wife is a cause of reward. Sayyiduna Abu Dharr (may Allah be pleased with him) said: How will there be reward for me in my desire? The Messenger of Allah (peace and blessings be upon him) said: Tell me, if you had a son, he reached maturity, and you hoped for good from him, but he died—would you be patient over it? I said: Yes. The Prophet (peace and blessings be upon him) said: Did you create him? I said: No, rather Allah Almighty created him. The Prophet (peace and blessings be upon him) said: Did you guide him? I said: No, rather Allah Almighty guided him. The Prophet (peace and blessings be upon him) said: Did you provide for him? I said: No, rather Allah Almighty provided for him. The Prophet (peace and blessings be upon him) said: It is just like that; just as Allah Almighty fulfilled all the needs and necessities of the child, but you received reward for his death. In the same way, if you use your private part in a lawful place and avoid the unlawful, if Allah wills, He will protect it, and if He wills, He will cause it to die, and you will receive reward.
