The Ruling on Giving Charity on Behalf of the Deceased and Making Du'a at His Grave

Question:
Is it permissible to give charity on behalf of a deceased person after his death? It is known that making du'a for him has been reported, but should one raise their hands when making du'a while standing at the grave?

Answer:
There is no harm in giving charity; in fact, it is prescribed to give charity on behalf of the deceased, whether from his wealth that the heir inherited, or from other wealth, whether the one giving charity is an heir or not. It is established that he (peace and blessings be upon him) was asked; a man asked him, saying: "My mother died and she did not leave a bequest, and I think that if she had been able to speak, she would have given charity. Will she receive a reward if I give charity on her behalf?" The Prophet said: .
And he (peace and blessings be upon him) said: . So if his righteous son makes du'a for him and gives charity on his behalf, it benefits him... and likewise, if someone other than his son from among the Muslims makes du'a for him: from brothers, or sisters, or relatives, or others, or if some of his relatives or others give charity on his behalf, all of this is beneficial. Charity on behalf of the deceased is beneficial even from those who are not relatives.
Q: Is it prescribed to raise the hands?
The Shaykh: And raising the hands is likewise; there is no harm in raising them. Raising the hands is among the causes of the du'a being answered. It is established that he (peace and blessings be upon him) raised his hands for the du'a of the deceased. He visited al-Baqi' and raised his hands (peace and blessings be upon him) and made du'a for them. It is established from Aisha (may Allah be pleased with her) that he (peace and blessings be upon him) did that. So if one raises his hands and makes du'a, there is no harm or blame in that. Du'a is prescribed, and raising the hands is among the causes of the du'a being answered. In the authentic hadith, he (peace and blessings be upon him) says: .
But in the places where the Prophet (peace and blessings be upon him) did not raise his hands, we do not raise them. For example: the Friday sermon, and the festival sermon; the Prophet (peace and blessings be upon him) did not raise his hands in them, so we do not raise them. For example: after the obligatory prayer, when one says the taslim, one does not raise the hands; because the Prophet did not raise his hands after the obligatory prayer. Likewise, between the two prostrations, when one sits and makes du'a, one does not raise the hands. And at the end of the prayer, when one sits and makes du'a before saying the taslim, one does not raise the hands; because the Messenger did not raise his hands in these places. If it had been good, he (peace and blessings be upon him) would have done it, or his Companions would have done it.
As for the other places where nothing has been reported, the believer raises his hands when he makes du'a. Likewise, in the places where the Prophet (peace and blessings be upon him) raised his hands: such as the du'a for rain, or seeking aid, one raises his hands there; because the Messenger raised his hands there (peace and blessings be upon him). And likewise, if he makes an occasional du'a at some times, making du'a for his family or for the Muslims and raising his hands. All of this is good, there is no harm in it, and it is among the causes of the du'a being answered.
