مَنْهُومَانِ لَا يَشْبَعَانِ: مَنْهُومٌ فِي الْعِلْمِ لَا يَشْبَعُ مِنْهُ، وَمَنْهُومٌ فِي الدُّنْيَا لَا يَشْبَعُ مِنْهَا
Two eager seekers are never satisfied: one seeks knowledge and never has enough of it, and one seeks worldly things and never has enough of them.

مَنْهُومَانِ describes two people with intense appetite or craving. لَا يَشْبَعَانِ means “the two are not satisfied,” while لَا يَشْبَعُ refers to one person. The “hunger” is figurative, not literal physical hunger.
One person seeks more knowledge; another seeks increasing wealth, status, or worldly advantage. Both may want “more,” but their aims and results need not be equivalent.
Seeking knowledge should lead to benefit and action, while pursuit of worldly interests should remain within ethical limits.
