Abu Huraira reported: A man reviled Abu Bakr while the Prophet, peace and blessings be upon him, was sitting down. That made the Prophet impressed by Abu Bakr and he smiled. Then, Abu Bakr reviled the man with the same words as him and the Prophet became angry and he stood to leave. Abu Bakr went to the Prophet and he said, “O Messenger of Allah, the man reviled me and you were sitting, but when I responded you became angry and stood up.” The Prophet said, “Verily, there was an angel with you responding on your behalf, but Satan appeared when you responded with the same words as him and I will not sit in the presence of Satan.”

عَنْ أَبِي هُرَيْرَة أَنَّ رَجُلًا شَتَمَ أَبَا بَكْرٍ وَالنَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ جَالِسٌ فَجَعَلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَعْجَبُ وَيَتَبَسَّمُ فَلَمَّا أَكْثَرَ رَدَّ عَلَيْهِ بَعْضَ قَوْلِهِ فَغَضِبَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَامَ فَلَحِقَهُ أَبُو بَكْرٍ فَقَالَ يَا رَسُولَ اللَّهِ كَانَ يَشْتُمُنِي وَأَنْتَ جَالِسٌ فَلَمَّا رَدَدْتُ عَلَيْهِ بَعْضَ قَوْلِهِ غَضِبْتَ وَقُمْتَ قَالَ إِنَّهُ كَانَ مَعَكَ مَلَكٌ يَرُدُّ عَنْكَ فَلَمَّا رَدَدْتَ عَلَيْهِ بَعْضَ قَوْلِهِ وَقَعَ الشَّيْطَانُ فَلَمْ أَكُنْ لِأَقْعُدَ مَعَ الشَّيْطَانِ
