Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Whoever performs Hajj on behalf of his parents, or pays off a debt on their behalf, Allah Almighty will raise him on the Day of Resurrection with the righteous."
Al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator, Jabalah bin Sulayman, who is matruk (abandoned).
