From Sahih Muslim (Hadith 195):
Zuhair b. Harb said:Jarir reported on the authority of A'mash with this chain of transmitters that the Messenger of Allah (ﷺ) observed: By him in Whose hand is my life, you shall not enter Paradise unless you believe. The rest of the hadith is the same as narrated by Abd Mu'awiya and Waki
