Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: Sayyiduna Jibril (peace be upon him) came to the Prophet (peace and blessings be upon him) and said: "Your Lord has sent you greetings of peace, and He has sent me with this bunch of grapes so that you may eat it."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator, Hafs bin Umar bin Abi al-Attaf, and he is extremely weak.
