Sayyiduna Zayd bin Thabit (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "Jibril urged me about the neighbour, until I thought that he would make him an heir."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; its chain contains a narrator, al-Muttalib bin Abdullah bin Hantab, who is thiqah (trustworthy) but has some weakness; the rest of its narrators are the narrators of the "Sahih".
