I was allowed to speak of an angel from the angels of Allah who carry the Throne: (the distance) between his earlobe and shoulder covers a journey of seven hundred years
Authentic hadithعن جابر بن عبد الله رضي الله عنهما ، عن النبي صلى الله عليه وسلم قال: «أُذِنَ لي أنْ أُحَدِّثَ عن مَلَك مِن ملائكة الله مِن حَمَلَةِ العَرْش، إنَّ ما بين شَحْمةِ أُذُنِه إلى عاتِقِه مَسِيرةُ سبعِمائة عام».
Jābir ibn ‘Abdullāh (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "I was allowed to speak of an angel from the angels of Allah who carry the Throne: (the distance) between his earlobe and shoulder covers a journey of seven hundred years."
Explanation
In this Hadīth reported by Jābir (may Allah be pleased with him) the Prophet (may Allah's peace and blessings be upon him) explained that Allah, the Almighty, allowed him to inform his Ummah (community) of the description of one of the great angels of the angels of Allah, the Exalted; one of those who carry the greatest creation, the Throne of the Most Merciful. It would take a fast horse seven hundred years to cover the distance from the angel's earlobe to the bottom of his neck.
