‘Abdullaah Ibni Mas’ud radhi Allahu ‘anhu reported that a jewish scholar came to RasulAllah (may peace he upon him) and said: “Muhammad, or Abu al-Qasim, verily, Allah, the Exalted and Glorious will carry the Heavens on the Day of Judgment upon one finger and earths upon one finger and the mountains and trees upor one finger and the ocean and moist earth upon one finger -in fact the whole of the creation upon one finger, and then He will stir them and say:
‘I am your Lord, I am your Lord.’” Thereupon Allah’s Messenger (ﷺ) smiled testifying what that scholar had said. He then recited this verse: “And they honour not Allah with the honour due to Him; and the whole earth will be in His grip on the Day of Resurrection and the heavens rolled up in His right hand. Glory be to Him I and highly Exalted is He above what they associate (with Him).” (Surat az-Zumar, verse 67) (Sahih Muslim, Characteristics of the Day of Judgment, Paradise, and Hell Book 53, Hadith 7223)
Narrated `Abdullah:
A Jew came to the Prophet (ﷺ) and said, “O Muhammad! Allah will hold the heavens on a Finger, and the mountains on a Finger, and the trees on a Finger, and all the creation on a Finger, and then He will say, ‘I am the King.’” On that Allah’s Messenger (ﷺ) smiled till his premolar teeth became visible, and then recited: ‘No just estimate have they made of Allah such as due to him (az Zumar 39/67) `Abdullah added: Allah’s Messenger (ﷺ) smiled (at the Jew’s statement) expressing his wonder and belief in what was said. [Sahih al-Bukhari #7414]
The Prophet Muhammad (upon him be blessings and peace) said, “All the hearts of the offspring of Adam are between two fingers of Ar-Rahman. He turns it (in any direction) as He wills.” (Muslim and Ahmad)
Then Allah’s Messenger said:
‘O Turner of the Hearts – keep my heart firm on Your Religion.’ [Sahih Muslim]
