Is it permissible for the Mu'takif to defend himself.
حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَبْدِ اللَّهِ، قَالَ أَخْبَرَنِي أَخِي، عَنْ سُلَيْمَانَ، عَنْ مُحَمَّدِ بْنِ أَبِي عَتِيقٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَلِيِّ بْنِ الْحُسَيْنِ ـ رضى الله عنهما ـ أَنَّ صَفِيَّةَ، أَخْبَرَتْهُ. حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، قَالَ سَمِعْتُ الزُّهْرِيَّ، يُخْبِرُ عَنْ عَلِيِّ بْنِ الْحُسَيْنِ، أَنَّ صَفِيَّةَ ـ رضى الله عنها ـ أَتَتِ النَّبِيَّ صلى الله عليه وسلم وَهْوَ مُعْتَكِفٌ، فَلَمَّا رَجَعَتْ مَشَى مَعَهَا، فَأَبْصَرَهُ رَجُلٌ مِنَ الأَنْصَارِ، فَلَمَّا أَبْصَرَهُ دَعَاهُ فَقَالَ " تَعَالَ هِيَ صَفِيَّةُ ـ وَرُبَّمَا قَالَ سُفْيَانُ هَذِهِ صَفِيَّةُ ـ فَإِنَّ الشَّيْطَانَ يَجْرِي مِنَ ابْنِ آدَمَ مَجْرَى الدَّمِ ". قُلْتُ لِسُفْيَانَ أَتَتْهُ لَيْلاً قَالَ وَهَلْ هُوَ إِلاَّ لَيْلٌ
Narrated `Ali bin Al-Husain from Safiya: Safiya went to the Prophet (ﷺ) while he was in I`tikaf. When she returned, the Prophet (ﷺ) accompanied her walking. An Ansari man saw him. When the Prophet (ﷺ) noticed him, he called him and said, "Come here. She is Safiya. (Sufyan a sub-narrator perhaps said that the Prophet (ﷺ) had said, "This is Safiya"). And Satan circulates in the body of Adam's offspring as his blood circulates in it." (A sub-narrator asked Sufyan, "Did Safiya visit him at night?" He said, "Of course, at night.")
