Musnad Abu Ya'la al-Mawsili 242:2

Ishaq narrated to us, Jarir ibn Abd al-Hamid narrated to us, from Dawud al-Basri, from Abu Muslim al-Bajali, who said: I heard Zayd ibn Arqam saying: I reached the Prophet, may Allah bless him and grant him peace, while he was supplicating at the end of the prayer, and he was saying—then he mentioned the like of it or similar to it.
