Musannaf Ibn Abi Shayba 3:5935

8312. Abd al-A’la narrated to us, from al-Jurayri, from Hassan ibn Umayr, from Abd al-Rahman ibn Samurah—and he was one of the companions of the Messenger of Allah, may Allah bless him and grant him peace—who said: I was shooting arrows in Medina during the lifetime of the Messenger of Allah, when the sun eclipsed. So I cast them aside and said, "By Allah, I will certainly look at what has happened to the Messenger of Allah, may Allah bless him and grant him peace, regarding the eclipse of the sun." He said: So I came to him while he was standing in prayer, raising his hands. He said: He began to glorify Allah (tasbih), praise Him (tahmid), declare His greatness (takbir), declare His oneness (tahlil), and supplicate until it (the eclipse) cleared from it. He said: When it cleared from it, he recited two surahs and prayed two rak'ahs.
