It was narrated that Ibn 'Abbas (رضي الله عنه) said:

A Jewish man passed by the Messenger of Allah (ﷺ) when he was sitting, and said: What will you say, O Abul-Qasim, on the day when Allah puts the sky on this - and he gestured with his forefinger - and the earth on this, the water on this, the mountains on this and all of creation on this? [And he] gestured each time with his fingers. Then Allah revealed the words: “They made not a just estimate of Allah such as is due to Him" [az-Zumar 39:67].
