Jami` at-Tirmidhi Book 47, Hadith 417
“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 idolaters were saying to the Messenger of Allah: ‘Name the lineage of your Lord for us.’ So Allah, Most High, revealed: Say: “He is Allah, the One. Allah As-Samad.” So As-Samad is ‘the One Who does not beget, nor is He begotten,’ because there is nothing born except it will die, and there is nothing that dies except that it will be inherited from, and verily. Allah, the Mighty and Sublime, does not die, nor is He inherited from. ‘And there is none comparable to Him.’ He said: ‘There is nothing similar to Him, nor equal to Him, nor is there anything like Him.’”
“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).’”
