Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The most severely punished of people on the Day of Resurrection will be the scholar whose knowledge did not benefit him."
Tabarani recorded it in al-Mu'jam al-Saghir; its chain contains Uthman al-Burri. Al-Fallas says: He is saduq (truthful) but makes many mistakes and is a man of innovation. Ahmad, al-Nasa'i (may Allah have mercy on him) and al-Daraqutni (may Allah have mercy on him) declared him da'if (weak).
