Jami` at-Tirmidhi Book 47, Hadith 418
“The Prophet looked at the moon and he said: ‘O Aishah! Do you seek refuge with Allah from the evil of this? For indeed this is Al-Ghasiqu Idha Waqab (The darkened one as it darkens).’”
“The Prophet mentioned their (the idolater’s) gods, so they said: ‘Then name your Lord’s lineage for us.’” He said: “So Jibril, peace be upon him, came to him with this Surat: Say: “He is Allah, the One.” So he mentioned similarly, but he did not say in it: “From Ubayy bin Ka’b.” And this is more correct than the narration of Abu Sa’eed (no. 3364). Abu Sa’eed’s name is Muhammad bin Muyassar.
the Prophet said: “Allah has revealed to me Ayat the likes of which have not been seen: “Say: I seek refuge in the Lord of mankind…” until the end of the Surat. “Say: I seek refuge in the Lord of Al-Falaq…” until the end of the Surat.
