Hadith: Allah will grab the earth and roll up the heavens in His right Hand, then, He will say: 'I am the King. Where are the kings of the earth?'

عَنْ أَبِي هُرَيْرَةَ رضي الله عنه قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ:
«يَقْبِضُ اللَّهُ الأَرْضَ، وَيَطْوِي السَّمَوَاتِ بِيَمِينِهِ، ثُمَّ يَقُولُ: أَنَا المَلِكُ، أَيْنَ مُلُوكُ الأَرْضِ».
[صحيح] - [متفق عليه] - [صحيح البخاري: 4812]

Abu Hurayrah (may Allah be pleased with him) reported that he heard the Messenger of Allah (may Allah's peace and blessings be upon him) say:
"Allah will grab the earth and roll up the heavens in His right Hand, then, He will say: 'I am the King. Where are the kings of the earth?'"
Sahih/Authentic. - [Al-Bukhari and Muslim]

Explanation

The Prophet (may Allah's peace and blessings be upon him) informed that on the Day of Judgment, Allah Almighty will grab the earth and fold it, and will roll up the heavens with His right Hand and wrap them above each other and exterminate them. Then, He will say: I am the King, where are the kings of the earth?!
