Musnad Ahmad 31:12

Abu Amir narrated to us, Zubayr ibn Abdullah narrated to us, Rabih ibn Abi Sa'id al-Khudri narrated to me, from his father, who said: We said on the day of the Trench: "O Messenger of Allah, is there anything we should say? For the hearts have reached the throats." He said: "Yes, 'O Allah, cover our vulnerabilities and secure our fears.'" He said: "Then Allah, the Almighty and Majestic, struck the faces of His enemies with the wind, and Allah, the Almighty and Majestic, defeated them by the wind."
