الطبراني:٨٧٤٨ – حَدَّثَنَا مُحَمَّدُ بْنُ النَّضْرِ الْأَزْدِيُّ ثنا مُعَاوِيَةُ بْنُ عَمْرٍو ثنا زَائِدَةُ عَنْ مَنْصُورٍ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ عَنْ أَبِيهِ عَنْ عَبْدِ اللهِ قَالَ

«إِنَّ الْإِثْمَ حَوَازُّ الْقُلُوبِ فَمَا حَزَّ فِي قَلْبِ أَحَدِكُمْ شَيْءٌ فَلْيَدَعْهُ»
