Musannaf Ibn Abi Shayba 3:2403

Yazid ibn Harun narrated to us, he said: Ibn Abi Dhi’b informed us, from al-Maqburi, from ‘Abd al-Rahman ibn Abi Sa’id al-Khudri, from his father, who said: We were detained on the day of the Trench from the Dhuhr, ‘Asr, Maghrib, and ‘Isha’ prayers until we were spared that. And that is His saying, the Exalted: "And Allah spared the believers the fighting, and Allah is Powerful, Exalted in Might." Then the Messenger of Allah (peace be upon him) stood up and ordered Bilal, so he performed the Iqamah for the prayer. Then he prayed Dhuhr just as he used to pray it before that. Then he performed the Iqamah and prayed ‘Asr just as he used to pray it before that. Then he performed the Iqamah and prayed Maghrib just as he used to pray it before that. Then he performed the Iqamah for ‘Isha’ and prayed it just as he used to pray it before that, before the revelation of: "But if you fear, then [pray] on foot or riding."
