‘Urwah reported: Aisha, may Allah be pleased with her, said, “Verily, the first trial to occur in this nation after the passing of its Prophet, peace and blessings be upon him, was people eating to their fill. For when people fill their stomachs, their bodies are fattened, their hearts are hardened, and their desires are uncontrollable.”

عَنْ عُرْوَةَ قَالَ قَالَتْ عَائِشَةُ رضي الله عنها إِنَّ أَوَّلَ بَلاءٍ حَدَّثَ فِي هَذِهِ الأُمَّةِ بَعْدَ قَضَاءِ نَبِيِّهَا صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الشِّبَعُ فَإِنَّ الْقَوْمَ لَمَّا شَبِعَتْ بُطُونَهُمْ سَمِنَتْ أَبْدَانُهُمْ فَتَصَعَّبَتْ قُلُوبُهُمْ وَجَمَحَتْ شَهَوَاتُهُمْ
