Musnad Ahmad 482:123

Abu Abd al-Rahman narrated to us, Musa—meaning Ibn Ayyub al-Ghafiqi—narrated to me, my paternal uncle Iyas ibn Amir narrated to me, he said: I heard Uqbah ibn Amir al-Juhani saying: When "Glorify the name of your Lord, the Great" [Al-Waqi'ah: 74] was revealed, the Messenger of Allah (peace and blessings of Allah be upon him) said to us: "Place it in your bowing (ruku)." Then, when "Glorify the name of your Lord, the Most High" [Al-A'la: 1] was revealed, he said: "Place it in your prostration (sujud)."
