Musnad Ahmad 770:98

Waki’ narrated to us, Ismail bin Abi Khalid narrated to us, from Qais bin Abi Hazim, from Jarir bin Abdullah, who said: We were sitting with the Prophet, peace and blessings of Allah be upon him, and he looked at the moon on the night of the full moon and said: "Verily, you will be presented before your Lord, the Almighty and Majestic, and you will see Him just as you see this moon; you will not be crowded in seeing Him. So, if you are able to not be overcome regarding a prayer before the rising of the sun and before its setting, then do so." Then he recited: {And exalt [Allah] with praise of your Lord before the rising of the sun and before the setting} [Qaf: 39].
