Sayyiduna Abu al-Darda' (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "I fear three things for my Ummah: the slip of a scholar, a hypocrite's arguing on the basis of the Qur'an, and the denial of destiny (qadar)."
Al-Tabarani recorded it; its chain contains a narrator, Mu'awiyah bin Yahya al-Sadafi, who is da'if (weak).
