Mukhtasar Sahih Bukhari — Hadith 1754

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet Muhammad (peace and blessings be upon him) said: "On the Day of Resurrection, a big, fat man will come, but he will not be worth even the wing of a mosquito in the sight of Allah." Then he said: "Recite this verse (mentioned above): 'So on the Day of Resurrection, We shall assign no weight to them.'" (This is its meaning, Surah Al-Kahf, verse: 105)
