Majma al-Zawaid — Hadith 3657

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that his father sent him to the Prophet (peace and blessings be upon him) on some errand. Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says: I found the Prophet (peace and blessings be upon him) sitting with his Companions in the mosque, and I was not able to speak with him (peace and blessings be upon him). When he had offered the Maghrib prayer, he got up and he (peace and blessings be upon him) began offering voluntary prayers, until the people present in the mosque had gone away. He too went to his house, and I followed him. When he sensed my footsteps, he asked: "Who is it?" I said: "Ibn Abbas." The Prophet (peace and blessings be upon him) asked: "The cousin of the Messenger of Allah?" I said: "The cousin of the Messenger of Allah." The Prophet (peace and blessings be upon him) said: "Welcome to the cousin of the Messenger of Allah!"
Allamah al-Haythami says: I say: After this the narrator mentioned a hadith similar to the one reported in the "Sahih".
Al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator whom I do not know.
