A huge fat man will come on the Day of Judgment weighing less than a mosquito wing in the sight of Allah
Authentic hadithعن أبي هريرة رضي الله عنه عن رسول الله صلى الله عليه وسلم قال: «إنه لَيَأتي الرَّجلُ السَّمين العظيم يوم القيامة لا يَزِنُ عند الله جَناح بَعُوضة».
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "A huge fat man will come on the Day of Judgment weighing less than a mosquito wing in the sight of Allah."
Explanation
On the Day of Judgment, the huge bulky man who is proud in this world and behaves arrogantly and tyrannically in his words and actions will not be worth the weight of a mosquito wing in the sight of Allah, nor will he have any value or credit.
