What is the ruling on dedicating the reward of charity to the deceased?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling on giving charity on behalf of the deceased so that the deceased may receive the reward?

Answer:
This is good, if the deceased was a Muslim and you give charity and dedicate its reward to the deceased, this is good. Sa'd ibn 'Ubadah (may Allah be pleased with him) asked when his mother died and she had not given charity, and if her tongue had not been held back, or if she had been able to speak, she would have given charity. He asked: Shall I give charity on her behalf? He said: Yes. Charity on behalf of the deceased is permissible, and it carries reward and merit, and the Sunnah has come regarding it. Yes.
