Musannaf Ibn Abi Shaybah 31729 — The supplication on seeing the new

Abd al-Rahman bin Harmalah said: I was returning with Sa'id bin al-Musayyib, and we said: "O Abu Muhammad, this is the new moon." When he saw it, he said: "I believe in the One who created you, then proportioned you and fashioned you rightly." Then he turned to me and said: "When the Messenger of Allah (peace and blessings be upon him) saw the new moon, he would supplicate like this."
