Abu al-Tufayl reported: It was said to Hudhayfah ibn al-Yaman, may Allah be pleased with him, “What do you mean by your statement: The dead person is not one relieved by death, but rather the truly dead person is dead among the living?” Hudhayfah said, “It is one who does not reject evil with his hand, nor his tongue, nor his heart.”

عَنْ أَبِي الطُّفَيْلِ قَالَ قِيلَ لِحُذَيْفَةَ بْن الْيَمَان رضي الله عنه مَا تَعْنِي بِقَوْلِكَ لَيْسَ مَنْ مَاتَ فَاسْتَرَاحَ بِمَيِّتٍ إِنَّمَا الْمَيِّتُ مَيِّتُ الأَحْيَاءِ قَالَ هُوَ الَّذِي لا يُنْكِرُ الْمُنْكَرَ بِيَدِهِ وَلا بِلِسَانِهِ وَلا بِقَلْبِهِ
