[Machine] It was narrated that the Messenger of Allah ﷺ said: "There is no making vows in disobedience or in what the son of Adam does not possess." Al-Shafi'i (may Allah have mercy on him) said that this hadith was narrated by 'Abd al-Wahhab al-Thaqafi with this chain of narration: A woman from the Ansar made a vow and fled on a camel to the Prophet ﷺ , saying: "If Allah saves me (from danger), I will sacrifice the camel." The Prophet ﷺ said: "This statement," and he took her camel. Al-Shafi'i (may Allah have mercy on him) said: "He did not command her to sacrifice it like she said, nor did he make her offer expiation." Al-Shafi'i (may Allah have mercy on him) said: "We say concerning this matter that whoever vows to offer as a sacrifice something that he does not own, the vow is not binding upon him. And whoever vows to do something that he is unable to do, the vow is not binding upon him because he does not possess the ability to do it. So it is like he does not possess anything else besides it."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا نَذْرَ فِي مَعْصِيَةٍ وَلَا فِيمَا لَا يَمْلِكُ ابْنُ آدَمَ قَالَ الشَّافِعِيُّ رَحِمَهُ اللهُ وَكَانَ فِي حَدِيثِ عَبْدِ الْوَهَّابِ الثَّقَفِيِّ بِهَذَا الْإِسْنَادِ أَنَّ امْرَأَةً مِنَ الْأَنْصَارِ نَذَرَتْ وَهَرَبَتْ عَلَى نَاقَةٍ لِلنَّبِيِّ ﷺ إِنْ نَجَّاهَا اللهُ عَلَيْهَا لَتَنْحَرَنَّهَا فَقَالَ النَّبِيُّ ﷺ هَذَا الْقَوْلَ وَأَخَذَ نَاقَتَهُ قَالَ الشَّافِعِيُّ رَحِمَهُ اللهُ وَلَمْ يَأْمُرْهَا أَنْ تَنْحَرَ مِثْلَهَا وَلَا تُكَفِّرَ قَالَ الشَّافِعِيُّ رَحِمَهُ اللهُ فَبِذَلِكَ نَقُولُ إِنَّ مَنْ نَذَرَ تَبَرُّرًا أَنْ يَنْحَرَ مَالَ غَيْرِهِ فَالنَّذْرُ سَاقِطٌ عَنْهُ وَمَنْ نَذَرَ مَا لَا يُطِيقُ أَنْ يَعْمَلَهُ بِحَالٍ سَقَطَ النَّذْرُ عَنْهُ لِأَنَّهُ لَا يَمْلِكُ أَنْ يَعْمَلَهُ فَهُوَ كَمَا لَا يَمْلِكُ مَا سِوَاهُ
