Musannaf Ibn Abi Shaybah 31733 — The supplication on seeing the new

Qatadah said that when the Prophet of Allah (peace and blessings be upon him) saw the new moon, he would say: "A moon of good and guidance, a moon of guidance and good, and a moon of good and guidance. I believe in the One who created you," three times. Then he would recite: "All praise is for Allah, who has taken away the moon of such-and-such and has brought the moon of such-and-such."
