Musannaf Ibn Abi Shaybah

Hazrat Shu’bah says that I was taking Hazrat Ibn Abbas (may Allah be pleased with them) on the day of Eid when he heard people reciting the Takbeer. He asked, “What is the matter with the people?” I said, “They are reciting the Takbeer.” He said, “Why are they reciting the Takbeer? Has the Imam recited the Takbeer?” I said, “No.” He said, “Are these people mad or what?”
