Abu Khayr on Qulub: Hearts of believers merciful, hypocrites malicious

Isma’il ibn Nujayd reported: Abu al-Khayr, may Allah have mercy on him, said, “Hearts are containers. A heart filled with faith has signs of compassion for all Muslims, concern for their concerns, and is cooperative in their welfare. A heart filled with hypocrisy has signs of malice, rancor, dishonesty, and envy.”

عَنْ إِسْمَاعِيل بْن نُجَيْدٍ قال قال أَبُو الْخَيْرِ رحمه الله الْقُلُوبُ ظُرُوفٌ فَقَلْبٌ مَمْلُوءٌ إِيمَانًا وَعَلَامَتُهُ الشَّفَقَةُ عَلَى جَمِيعِ الْمُسْلِمِينَ وَالِاهْتِمَامُ بِمَا يُهِمُّهُمْ وَمُعَاوَنَتُهُمْ عَلَى مَصَالِحِهِمْ وَقَلْبٌ مَمْلُوءٌ نِفَاقًا وَعَلَامَتُهُ الْحِقْدُ وَالْغِلُّ وَالْغِشُّ وَالْحَسَدُ
