[Machine] The Messenger of Allah ﷺ said, "Faith and disbelief cannot coexist in the heart of a person, and truth and lie cannot coexist altogether, and betrayal and trustworthiness cannot coexist altogether."  

أحمد:٨٥٩٣حَدَّثَنَا حَسَنُ بْنُ مُوسَى حَدَّثَنَا ابْنُ لَهِيعَةَ حَدَّثَنَا أَبُو الْأَسْوَدِ عَنْ عَبْدِ اللهِ بْنِ رَافِعٍ عَنْ أَبِي هُرَيْرَةَ

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَجْتَمِعُ الْإِيمَانُ وَالْكُفْرُ فِي قَلْبِ امْرِئٍ وَلَا يَجْتَمِعُ الصِّدْقُ وَالْكَذِبُ جَمِيعًا وَلَا تَجْتَمِعُ الْخِيَانَةُ وَالْأَمَانَةُ جَمِيعًا
