Musannaf Ibn Abi Shayba 33:376

Muhammad ibn Fudayl narrated to us, from Muhammad ibn Sa’d al-Ansari, who said: Abdullah ibn Yazid ibn Rabi’ah al-Dimashqi narrated to me, saying: Abu al-Darda’ said: I traveled by night one night to the mosque. When I entered, I passed by a man who was prostrating, and he was saying: "O Allah, I am fearful and seeking refuge, so grant me refuge from Your punishment. I am a needy beggar, so provide for me from Your bounty. I am not free of sin so that I may offer an excuse, nor am I possessed of power so that I may seek victory; rather, I am a sinner seeking forgiveness." He said: So when morning came, Abu al-Darda’ began teaching them to his companions, out of admiration for them.
