Musannaf Ibn Abi Shaybah

Hazrat Mujahid heard someone reciting the takbeer during the ten days, so he said: Why did he not raise his voice! Indeed, I found such people that when one of them would recite the takbeer in the mosque, the entire mosque would tremble due to his voice, then that voice would reach the people of the valley until it reached the place of Abtah, and the place of Abtah would tremble due to the voice, and indeed, the foundation of all of them would be that one person.
