Messenger of Allah ﷺ said, "The most awful name in Allah's sight on the Day of Resurrection, will be (that of) a man calling himself Malik Al-Amlak (the king of kings).

قَالَ رَسُولُ اللَّهِ ﷺ أَخْنَى الأَسْمَاءِ يَوْمَ الْقِيَامَةِ عِنْدَ اللَّهِ رَجُلٌ تَسَمَّى مَلِكَ الأَمْلاَكِ

The vilest names in Allah’s sight on the Day of resurrection will be that of a man called Malik al-Amlak. Abu Dawud said: This tradition has also been transmitted by Shu'aib b. Abi Hamzah from Abi al-Zinad through different chain of narrators. This version has the words "akhna' ismin" (most obscene name) instead of "akhna ismin" (the vilest name).

النَّبِيَّ ﷺ قَالَ أَخْنَعُ اسْمٍ عِنْدَ اللَّهِ تَبَارَكَ وَتَعَالَى يَوْمَ الْقِيَامَةِ رَجُلٌ تَسَمَّى مَلِكَ الأَمْلاَكِ

[Machine] The Prophet ﷺ said, "The best of names near Allah is a man named 'Milk Al-Amalak,' which means 'The King of Kings.'"

النَّبِيَّ ﷺ قَالَ «أَخْنَعُ الْأَسْمَاءِ عِنْدَ اللَّهِ رَجُلٌ تُسَمَّى بِمِلْكِ الْأَمْلَاكِ يَعْنِي شَاهَانِ شَاهَا »

Abu Hurayra reported that the Messenger of Allah ﷺ said, "The name which hates the most is that a man be called the King of Kings."

قَالَ رَسُولُ اللهِ ﷺ أَخْنَى الأسْمَاءِ عِنْدَ اللهِ رَجُلٌ تَسَمَّى مَلِكَ الأمْلاكِ
