Osman al-Khamis and his colleagues claim that Lady Fatima’s rage on Abu-Bakr is not an issue for him since he has been blessed and forgiven by God.

However they don’t notice to have a similar belief about Salman. It seems that Hazrat-e Salman has a higher place than Hazrat-e Fateima for them:

حدثنا ‏ ‏محمد بن حاتم ‏ ‏حدثنا ‏ ‏بهز ‏ ‏حدثنا ‏ ‏حماد بن سلمة ‏ ‏عن ‏ ‏ثابت ‏ ‏عن ‏ ‏معاوية بن قرة ‏ ‏عن ‏ ‏عائذ بن عمرو ‏

قَوْله : ( أَنَّ أَبَا سُفْيَان أَتَى عَلَى سَلْمَان وَصُهَيْبٍ وَبِلَال فِي نَفَر فَقَالُوا : مَا أَخَذَتْ سُيُوف اللَّه مِنْ عُنُق عَدُوّ اللَّه مَأْخَذهَا ) ‏
‏ضَبَطُوهُ بِوَجْهَيْنِ : أَحَدهمَا بِالْقَصْرِ وَفَتْح الْخَاء , وَالثَّانِي بِالْمَدِّ وَكَسْرهَا , وَكِلَاهُمَا صَحِيح , وَهَذَا الْإِتْيَان لِأَبِي سُفْيَان كَانَ وَهُوَ كَافِر فِي الْهُدْنَة بَعْد صُلْح الْحُدَيْبِيَة . وَفِي هَذَا فَضِيلَة ظَاهِرَة لِسَلْمَان وَرُفْقَته هَؤُلَاءِ وَفِيهِ مُرَاعَاة قُلُوب الضُّعَفَاء وَأَهْل الدِّين وَإِكْرَامهمْ وَمُلَاطَفَتهمْ . ‏

‏قَوْله : ( يَا إِخْوَتاه أَغْضَبْتُكُمْ ؟ قَالُوا : لَا , يَغْفِر اللَّه لَك يَا أُخَيّ ) ‏
‏أَمَّا قَوْلهمْ : ( يَا أُخَيّ ) فَضَبَطُوهُ بِضَمِّ الْهَمْزَة عَلَى التَّصْغِير , وَهُوَ تَصْغِير تَحْبِيب . وَتَرْقِيق وَمُلَاطَفَة . وَفِي بَعْض النُّسَخ بِفَتْحِهَا . قَالَ الْقَاضِي : قَدْ رُوِيَ عَنْ أَبِي بَكْر أَنَّهُ نَهَى عَنْ مِثْل هَذِهِ الصِّيغَة , وَقَالَ : قُلْ :عَافَاك اللَّه , رَحِمَك اللَّه , لَا تَزِدْ . أَيْ لَا تَقُلْ قَبْل الدُّعَاء لَا فَتَصِير صُورَته صُورَة نَفْي الدُّعَاء . قَالَ بَعْضهمْ : قُلْ : لَا , وَيَغْفِر لَك اللَّه

Abu-sofian (he wasnot Muslim yet) came toward Salman , Sahib, Belal and some others, they told him: Swear to God that his swords were not put on the necks of his enemies (they meant him). Abu-Bakr said: Are you saying this to the master and Sheikh of Ghuraish? A while later, Prophet (pbuh) came and addressed Abu-Bakr: whilst if you’d made them furious; because if you did, it is like you’d made your god furious. Then Abu-Bakr went to them and said: O brothers, did I make you furious? They said: no. God may forgive you and bless you O brother.

منبع : صحيح مسلم ـ فضائل الصحابة ـ من فضائل سلمان وصهيب وبلال رضي الله عنهم

( وَمَن يُوَلِّهِمْ يَوْمَئِذٍ دُبُرَهُ إِلاَّ مُتَحَرِّفاً لِّقِتَالٍ أَوْ مُتَحَيِّزاً إِلَى فِئَةٍ فَقَدْ بَاء بِغَضَبٍ مِّنَ اللّهِ وَمَأْوَاهُ جَهَنَّمُ وَبِئْسَ الْمَصِير)
ُ {الأنفال/16} )

Who will defend the first caliph?

First: Abu-Sofian was a disbeliever. So why did Abu-Bakr defend him?

Second: the fury of Salman and Sohaib and Belal is God’s fury.

Summary:

Why Abu-Bakr defended a disbeliver who is God’s enemy?

If Hazrat-e Zahra’s rage is not harm to first caliph, why the rage of Salman and his companions are harmful to him?

While the rage of God is the rage of Hazrat-e Zahra:

(ان الله يغضب لغضبك ويرضى لرضاك) 

المستدرك : 3/154 مجمع الزوائد : 9/203

The rage of Hazrat-e Zahra (pbuh) is the rage of Prophet Muhammad (Pbuh):

( فاطمة بضعة مني فمن آذاها فقد آذاني )

صحيح بخاري : 6/491 , 8/110 فتح الباري : 7/84

It’s written in this documents that Hazrat-e Zahra passed away while she was angry with Abu-Bakr and she didn’t talk to him in her life till death.

Meanwhile, the holy Quran says:

( ان الذين يؤذون الله ورسوله لعنهم الله في الدنيا والآخرة )

( والذين يؤذون رسول الله لهم عذاب أليم )
