Musannaf Ibn Abi Shaybah

Hazrat Abdur Rahman bin Harmalah narrates that I came out of the mosque with Hazrat Saeed bin Musayyib. We said, "O Abu Muhammad! Look, the moon!" When he saw the moon, he said: "I believe in the Lord who created you, shaped you, and made your form balanced." Then he turned to me and said that the Holy Prophet (peace and blessings be upon him) used to say these words upon seeing the moon.
