Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) relates: Once I was performing tawaf with the Prophet (peace and blessings be upon him), and meanwhile he heard a man saying: "O Allah, forgive so-and-so son of so-and-so!" The Prophet (peace and blessings be upon him) asked: "What is the reason for this?" He said: "A man instructed me to supplicate for him." The Prophet (peace and blessings be upon him) said: "Your companion has been forgiven (what is meant here is: because you supplicated for him in his absence, this supplication was accepted)."
Imam al-Tabarani recorded this narration; its chain contains a narrator, al-Harith bin Imran al-Ja'fari, and he is da'if (weak).
