When the Messenger of Allah (ﷺ) saw the new moon, he turned away his face from it.

Abu Dawud said: On this subject there is no tradition which has perfect chain and is sound.
Sunan Abi Dawud Book 43, Hadith 321
← Previous Hadith When the Prophet of Allah (ﷺ) saw the new moon, he said: "a new moon of good and right guidance; a new moon of good and right guidance; a new moon of good and right guidance. I believe in Him Who created you" three times. He would then say: "Praise be to Allah Who has made such and such a month to pass and has brought such and such a month."

Sunan Abi Dawud Book 43, Hadith 320 Next Hadith → The Messenger of Allah (ﷺ) never went out of my house without raising his eye to the sky and saying: "O Allah! I seek refuge in Thee lest I stray or be led astray, or slip or made to slip, or cause injustice, or suffer injustice, or do wrong, or have wrong done to me."
