Sayyiduna Sakhr (may Allah be pleased with him), who lived in the time of the Prophet (peace and blessings be upon him), narrates that the Prophet (peace and blessings be upon him) said: "Do not hurt the living by reviling those who have passed away."
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Saghir. He recorded these words from the Prophet (peace and blessings be upon him): "Do not revile those disbelievers whose children have become Muslims." Its chain contains a narrator, Abdullah bin Sa'id bin Abi Maryam, and he is da'if (weak).
