Sayyiduna Talq bin Ali (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "He is not a believer whose neighbour is not safe from his bawa'iq (i.e., his evil)."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; its chain contains a narrator, Ayyub bin Utbah, whom the majority declared da'if (weak); he is saduq (truthful) but makes many mistakes.
