Sahih Muslim Book 39, Hadith Number 6701.

Abdullah reported that a person from the People of the Book came to Allah’s Apostle (may peace he upon him) and said: Abu al-Qasim, verify, Allah would carry tho upon one finger and the earths upon one finger and the trees and moist earth upon one finger and in fact the whole of the creation upon one finger and then say: I am your Lord. I an your Lord. And he (the narrator) further said: I saw Allah’s Messenger (may peace be upon him) feeling so much happy that his front teeth became visible and then he recited the Yeife: “And they honour not Allah with the honour due to Him” (xxxix. 67).
