And on the Day of Resurrection the whole earth will be in His grip, and the heavens will be rolled up in His right hand!

Imām Ibn Mandah reported:

Sufyān narrated to us, from Manṣūr; and Sulaymān, from Ibrāhīm, from ʿUbaydah, from ʿAbd Allāh:

A Yahūdī came to the Prophet ﷺ and said: “Indeed, Allāh holds the heavens upon one finger, and the earths upon one finger, and the mountains upon one finger, and the trees upon one finger, and the creatures upon one finger!”

Then the Prophet ﷺ laughed until his molars became visible. Then he said: “And they did not appraise Allāh with true appraisal.” (al-An’ām:91)

Yaḥyā ibn Saʿīd said: And al-Fuḍayl ibn ʿIyāḍ narrated to me, from Manṣūr, from Ibrāhīm, from ʿUbaydah, from ʿAbd Allāh, who said: The Prophet ﷺ laughed — out of amazement and in affirmation of what the Yahūdī said.
