Jabir ibn Abdullah (may Allah be pleased with him) narrated: I said, “O Messenger of Allah! May my father be sacrificed for you, tell me about the thing which Allah created first?” The Prophet ﷺ said, “O Jabir! Indeed Allah, before all things, created the light of your Prophet from His own light, and made that light such that it could fly wherever it wished by its power and might. At that time there was no Preserved Tablet, no pen, no Paradise nor Hellfire, there were no angels, no heavens and earth, no sun nor moon, neither jinn nor humans.”
The Throne was swaying on the water; when the Kalima was written on it, it became still.
Ibn Abbas (may Allah be pleased with them both) narrated that Allah revealed to Isa (peace be upon him) and said: Believe in Muhammad ﷺ, and tell your followers that whoever among them lives to see Muhammad ﷺ, he too should believe in him.
Because if Muhammad did not exist, Adam would not exist, nor would Paradise and Hellfire be created. Indeed, when Allah created the Throne and placed it on the water, it began to shake, so Allah wrote on the Throne لا اله الا الله محمد رسول الله, and it became still.
Verification of the Hadith:
Imam al-Dhahabi said:
I consider this to be a fabrication.
