أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ جَعْفَرٍ الرَّقِّيُّ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَمْرٍو، عَنْ زَيْدٍ هُوَ ابْنُ أَبِي أُنَيْسَةَ، عَنْ سَيَّارٍ، عَنْ الْحَسَنِ، قَالَ: "مَنْهُومَانِ لَا يَشْبَعَانِ: مَنْهُومٌ فِي الْعِلْمِ لَا يَشْبَعُ مِنْهُ، وَمَنْهُومٌ فِي الدُّنْيَا لَا يَشْبَعُ مِنْهَا، فَمَنْ تَكُنِ الْآخِرَةُ هَمَّهُ، وَبَثَّهُ، وَسَدَمَهُ، يَكْفِي اللَّهُ ضَيْعَتَهُ، وَيَجْعَلُ غِنَاهُ فِي قَلْبِهِ، وَمَنْ تَكُنِ الدُّنْيَا هَمَّهُ، وَبَثَّهُ، وَسَدَمَهُ، يُفْشِي اللَّهُ عَلَيْهِ ضَيْعَتَهُ، وَيَجْعَلُ فَقْرَهُ بَيْنَ عَيْنَيْهِ، ثُمَّ لَا يُصْبِحُ إِلَّا فَقِيرًا، وَلَا يُمْسِي إِلَّا فَقِيرًا".
Imam Hasan al-Basri (may Allah have mercy on him) said: Two types of greedy people are never satisfied: one who is greedy for knowledge, who is never satiated with knowledge, and the other who desires the world, who is never satiated with worldly things. So, whoever’s concern, intention, preoccupation, desire, and remembrance is all for the Hereafter, Allah will suffice him in all his affairs and work, and will place richness in his heart. And whoever’s concern, desire, and love is for the world, Allah will scatter his affairs, and will write poverty and need between his two eyes, so that he will be poor in the morning and poor in the evening.
