The Ruling and Method of Offering the Reward to the Deceased

Question:
Regarding offering the reward of Hajj and 'Umrah, as a voluntary act, does it reach the deceased?

Answer:
To the deceased and the elderly.
Q: And is this voluntary act established from the Messenger of Allah (peace and blessings be upon him)?
The Shaykh: The hadith is general.
Q: And voluntary fasting?
The Shaykh: Yes, fasting... obligatory fasting is performed, the fasting of the obligation. The Prophet (peace and blessings be upon him) said: meaning his relative.
Q: Did not all the hadiths regarding fasting come in response to questions about the obligation?
The Shaykh: The voluntary act is like... the hadith of Shubruma does not mention an obligation. When he heard him saying: "Labbaik for Shubruma." He said: He said: "A brother of mine or a relative." He said: He said: "No," he said: and he did not ask him whether it was an obligation or a voluntary act.
Q: Offering the reward to the deceased through charity and others?
The Shaykh: The same charity, one gives charity with the intention for him, intending it for him, or Hajj or 'Umrah or supplication.
Q: Some people say that its reward reaches, or that they offer it to so-and-so, for example?
The Shaykh: ... the intention, Allah knows what is in his heart. If he intends it with his heart; that is sufficient. If he intends it for so-and-so, that is sufficient. He knows the unseen and knows what is in hearts.
