Sayyidah Aishah Siddiqah (may Allah be pleased with her) narrates: "You were commanded to pray for forgiveness for your predecessors, and you revile them. I heard the Prophet (peace and blessings be upon him) say: 'This Ummah will not perish until the people of its last era curse those who came first.'"
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Isma'il bin Ibrahim bin Muhajir, who is da'if (weak).
