Ibn al-Jawzi reported: Abu Bakr al-Warraq, may Allah have mercy on him, said, “The source of overpowering whims is approaching what is lusted. When whims overpower the heart, it will commit wrong. When the heart commits wrong, the chest will be tightened. When the chest is tightened, character will be bad. When character is bad, the creation will hate him. When the creation hates him, he will hate them. When he hates them, he will be harsh with them. When he is harsh with them, he becomes an accursed devil.”

عن ابن الجوزي قَالَ أَبُو بَكْرٍ الْوَرَّاقُ رحمه الله أَصْلُ غَلَبَةِ الْهَوَى مُقَارَبَةُ الشَّهَوَاتِ فَإِذَا غَلَبَ الْهَوَى أَظْلَمَ الْقَلْبُ وَإِذَا أَظْلَمَ الْقَلْبُ ضَاقَ الصَّدْرُ وَإِذَا ضَاقَ الصَّدْرُ سَاءَ الْخُلُقُ وَإِذَا سَاءَ الْخُلُقُ أَبْغَضَهُ الْخَلْقُ وَإِذَا أَبْغَضَهُ الْخَلْقُ أَبْغَضَهُمْ وَإِذَا أَبْغَضَهُمْ جَفَاهُمْ وَإِذَا جَفَاهُمْ صَارَ شَيْطَانًا رَجِيمًا
