Sahih Muslim 2504
'A'idh b. Amr reported that Abu Sufyan came to Salman, Suhaib and Bilal in the presence of a group of persons. They said:
By Allah, the sword of Allah did not reach the neck of the enemy of Allah as it was required to reach. Thereupon Abu Bakr said: Do you say this to the old man of the Quraish and their chief? Then he came to Allah's Apostle (may peace be upon'him) and informed him of this. Thereupon he (the Holy Prophet) said: Abu Bakr, you have perhaps annoyed them and if you annoyed them you have in fact annoyed your Lord. So Abu Bakr came to them and said: O my brothers, I have annoyed you. They said: No, our brother, may Allah forgive you
حَدَّثَنَا مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا بَهْزٌ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ مُعَاوِيَةَ،
 بْنِ قُرَّةَ عَنْ عَائِذِ بْنِ عَمْرٍو، أَنَّ أَبَا سُفْيَانَ، أَتَى عَلَى سَلْمَانَ وَصُهَيْبٍ وَبِلاَلٍ فِي نَفَرٍ فَقَالُوا
 وَاللَّهِ مَا أَخَذَتْ سُيُوفُ اللَّهِ مِنْ عُنُقِ عَدُوِّ اللَّهِ مَأْخَذَهَا ‏.‏ قَالَ فَقَالَ أَبُو بَكْرٍ أَتَقُولُونَ هَذَا
 لِشَيْخِ قُرَيْشٍ وَسَيِّدِهِمْ فَأَتَى النَّبِيَّ صلى الله عليه وسلم فَأَخْبَرَهُ فَقَالَ ‏
"‏ يَا أَبَا بَكْرٍ لَعَلَّكَ
 أَغْضَبْتَهُمْ لَئِنْ كُنْتَ أَغْضَبْتَهُمْ لَقَدْ أَغْضَبْتَ رَبَّكَ ‏"‏ ‏.‏ فَأَتَاهُمْ أَبُو بَكْرٍ فَقَالَ يَا إِخْوَتَاهْ أَغْضَبْتُكُمْ
 قَالُوا لاَ يَغْفِرُ اللَّهُ لَكَ يَا أُخَىَّ ‏.‏
