[Machine] And so, every oppressor fears, for it will repel injustice from him and fight for him, and it will not abandon him. If he fights on behalf of the oppressed, then there is no strength or retribution against him. If it is said to him, "Drink alcohol," or "Eat carrion," or "Sell your slave," or "Acknowledge a debt," or "Give a gift and resolve a contract," or "Kill your father or brother in Islam," his capacity encompasses the saying of the Prophet (ﷺ): "A Muslim is the brother of a Muslim." Some people say that if it were said to him, "Drink alcohol," or "Eat carrion," or "Kill your son or father or a forbidden relative," it would not be within his capacity, for this is not an absolute necessity. Then he changes his mind and says, if it were said to him, "Kill your father or son," or "Sell this slave," or "Acknowledge a debt" or "Give a gift," he would be bound by analogical reasoning. However, we prefer and say that the sale, gift, and every contract in that regard are invalid. Therefore, distinguish between every forbidden relative and others without any book or Sunnah. The Prophet (ﷺ) said: "Ibrahim (Abraham) said to his wife, 'This is my sister. And this is in the sight of Allah.'" And An-Nakha'i said: If the one taking an oath is an oppressor, then the intention is the oath-taker's, and if he is the oppressed, then the intention is the one taking the oath.

وَكَذَلِكَ كُلُّ مُكْرَهٍ يَخَافُ، فَإِنَّهُ يَذُبُّ عَنْهُ الْمَظَالِمَ وَيُقَاتِلُ دُونَهُ وَلاَ يَخْذُلُهُ، فَإِنْ قَاتَلَ دُونَ الْمَظْلُومِ فَلاَ قَوَدَ عَلَيْهِ وَلاَ قِصَاصَ، وَإِنْ قِيلَ لَهُ لَتَشْرَبَنَّ الْخَمْرَ، أَوْ لَتَأْكُلَنَّ الْمَيْتَةَ، أَوْ لَتَبِيعَنَّ عَبْدَكَ، أَوْ تُقِرُّ بِدَيْنٍ، أَوْ تَهَبُ هِبَةً وَتَحُلُّ عُقْدَةً، أَوْ لَنَقْتُلَنَّ أَبَاكَ أَوْ أَخَاكَ فِي الإِسْلاَمِ. وَسِعَهُ ذَلِكَ لِقَوْلِ النَّبِيِّ ﷺ: «الْمُسْلِمُ أَخُو الْمُسْلِمِ». وَقَالَ بَعْضُ النَّاسِ لَوْ قِيلَ لَهُ لَتَشْرَبَنَّ الْخَمْرَ، أَوْ لَتَأْكُلَنَّ الْمَيْتَةَ، أَوْ لَنَقْتُلَنَّ ابْنَكَ أَوْ أَبَاكَ أَوْ ذَا رَحِمٍ مَحْرَمٍ، لَمْ يَسَعْهُ، لأَنَّ هَذَا لَيْسَ بِمُضْطَرٍّ. ثُمَّ نَاقَضَ فَقَالَ إِنْ قِيلَ لَهُ لَنَقْتُلَنَّ أَبَاكَ أَوِ ابْنَكَ، أَوْ لَتَبِيعَنَّ هَذَا الْعَبْدَ، أَوْ تُقِرُّ بِدَيْنٍ أَوْ تَهَبُ، يَلْزَمُهُ فِي الْقِيَاسِ، وَلَكِنَّا نَسْتَحْسِنُ وَنَقُولُ الْبَيْعُ وَالْهِبَةُ وَكُلُّ عُقْدَةٍ فِي ذَلِكَ بَاطِلٌ. فَرَّقُوا بَيْنَ كُلِّ ذِي رَحِمٍ مُحَرَّمٍ وَغَيْرِهِ بِغَيْرِ كِتَابٍ وَلاَ سُنَّةٍ. وَقَالَ النَّبِيُّ ﷺ: «قَالَ إِبْرَاهِيمُ لاِمْرَأَتِهِ هَذِهِ أُخْتِي. وَذَلِكَ فِي اللَّهِ». وَقَالَ النَّخَعِيُّ إِذَا كَانَ الْمُسْتَحْلِفُ ظَالِمًا، فَنِيَّةُ الْحَالِفِ، وَإِنْ كَانَ مَظْلُومًا، فَنِيَّةُ الْمُسْتَحْلِفِ.
