لَا تَقُومُ السَّاعَةُ حَتَّى يَكُونَ أَسْعَدُ النَّاسِ بِالدُّنْيَا لُكَعُ ابْنُ لُكَعٍ
Translation: The Hour will not come until the person enjoying the greatest worldly fortune is a contemptible person, described as “lukaʿ son of lukaʿ.”

أَسْعَدُ النَّاسِ بِالدُّنْيَا points to someone enjoying great worldly fortune. لُكَعُ ابْنُ لُكَعٍ is a disparaging Arabic expression referring to a person lacking uprightness or nobility of character.
The report distinguishes worldly advantage from genuine moral excellence. Wealth, fame, and position do not in themselves establish honesty, justice, or good character.
