Hadith 8:1283
Abu Bakr narrated to us, he said: Abu Usama narrated to us, from Miskin Abu Hurayra, he said: I heard Mujahid, and a man said "Allahu Akbar" during the ten days [of Dhu al-Hijjah]. Mujahid said: "Would that he had raised his voice! For I have reached them [the predecessors], and a man would say 'Allahu Akbar' in the mosque, and the people of the mosque would shake with it, then the sound would go out to the people of the valley until it reached al-Abtah, and the people of al-Abtah would shake with it. And its origin was merely from one man."
حدثنا أبو بكر قال حدثنا أبو أسامة عن مسكين أبي هريرة قال سمعت مجاهدا وكبر رجل أيام العشر فقال مجاهد أفلا رفع صوته فلقد أدركتهم وإن الرجل ليكبر في المسجد فيرتج بها أهل المسجد ثم يخرج الصوت إلى أهل الوادي حتى يبلغ الأبطح فيرتج بها أهل الأبطح وإنما أصلها من رجل واحد
