عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَغْيَظُ رَجُلٍ عَلَى اللَّهِ يَوْمَ الْقِيَامَةِ وَأَخْبَثُهُ وَأَغْيَظُهُ عَلَيْهِ رَجُلٌ كَانَ يُسَمَّى مَلِكَ الْأَمْلَاكِ لَا مَلِكَ إِلَّا اللَّهُ عَزَّ وَجَلَّ
Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: On the Day of Resurrection, the most detested and wicked person in the sight of Allah Almighty will be the one who calls himself "Malik al-Amlak" (King of Kings), while there is no king except Allah Almighty.
