Question: What is the ruling regarding the congregational takbeer for the `Eed prayer.
Response: It has been legislated for a person to make takbeer from his home to the musallaa (area designated for the `Eed prayer), and whilst at the musallaa he should audibly (continue to) do so, each person unto himself, such that the place vibrates with the (sound of the) takbeer. As for them mutually agreeing to start and finish together (in congregation), then there is nothing (evidence) to indicate the permissibility of the congregational takbeer, and it has not been legislated.
