Mukhtasar Muslim (Abridged) 2148 — Allah’s saying: "We will not assign

Abu Huraira (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings be upon him) that he (peace and blessings be upon him) said: On the Day of Resurrection, a big, fat man will come who, in the sight of Allah, will not be equal to the wing of a mosquito. Recite this verse: "We shall not assign any weight for them on the Day of Resurrection." (That is, the fatness, wealth, and riches of the world will be of no use on the Day of Resurrection; there, only deeds are required. This hadith proves the condemnation of obesity.)
