Musannaf Ibn Abi Shaybah 9988 — What is said when the new moon is seen

Abd al-Rahman bin Harmalah said: I came out of the mosque with Sa'id bin al-Musayyib, and we said: "O Abu Muhammad! Look, the new moon!" When he saw the moon, he said: "I believe in the Lord who created you, fashioned you and made your form balanced." Then he turned to me and said: "The Prophet (peace and blessings be upon him) used to say these very words on seeing the new moon."
