Barirah came to seek my help regarding her manumission (freedom). I told herself you like I would pay your price to your masters but your Wala' (allegiance) would be for me." Her masters said, "If you like, you can pay what remains (of the price of her manumission), (Sufyan the sub-narrator once said), or if you like you can manumit her, but her (inheritance) Al-Wala would be for us. "When Messenger of Allah ﷺ came, I spoke to him about it. He said, "Buy her and manumit her. No doubt Al-Wala' is for the manumitted." Then Messenger of Allah ﷺ stood on the pulpit (or Messenger of Allah ﷺ ascended the pulpit as Sufyan once said), and said, "What about some people who impose conditions which are not present in Allah's Book (Laws)? Whoever imposes conditions which are not in Allah's Book (Laws), his conditions will be invalid even if he imposed them a hundred times."  

إِنْ شِئْتِ أَعْطَيْتُ أَهْلَكِ وَيَكُونُ الْوَلاَءُ لِي وَقَالَ أَهْلُهَا إِنْ شِئْتِ أَعْطَيْتِهَا مَا بَقِيَ وَقَالَ سُفْيَانُ مَرَّةً إِنْ شِئْتِ أَعْتَقْتِهَا وَيَكُونُ الْوَلاَءُ لَنَا فَلَمَّا جَاءَ رَسُولُ اللَّهِ ﷺ ذَكَّرَتْهُ ذَلِكَ فَقَالَ ابْتَاعِيهَا فَأَعْتِقِيهَا فَإِنَّ الْوَلاَءَ لِمَنْ أَعْتَقَ ثُمَّ قَامَ رَسُولُ اللَّهِ ﷺ عَلَى الْمِنْبَرِ وَقَالَ سُفْيَانُ مَرَّةً فَصَعِدَ رَسُولُ اللَّهِ ﷺ عَلَى الْمِنْبَرِ فَقَالَ مَا بَالُ أَقْوَامٍ يَشْتَرِطُونَ شُرُوطًا لَيْسَتْ فِي كِتَابِ اللَّهِ مَنِ اشْتَرَطَ شَرْطًا لَيْسَ فِي كِتَابِ اللَّهِ فَلَيْسَ لَهُ وَإِنِ اشْتَرَطَ مِائَةَ مَرَّةٍ قَالَ عَلِيٌّ قَالَ يَحْيَى وَعَبْدُ الْوَهَّابِ عَنْ يَحْيَى عَنْ عَمْرَةَ وَقَالَ جَعْفَرُ بْنُ عَوْنٍ عَنْ يَحْيَى قَالَ سَمِعْتُ عَمْرَةَ قَالَتْ سَمِعْتُ عَائِشَةَ رَوَاهُ مَالِكٌ عَنْ يَحْيَى عَنْ عَمْرَةَ أَنَّ بَرِيرَةَ وَلَمْ يَذْكُرْ صَعِدَ الْمِنْبَرَ  

Messenger of Allah ﷺ came to me and I told him about the slave-girl (Barirah) Messenger of Allah ﷺ said, "Buy and manumit her, for the Wala is for the one who manumits." In the evening the Prophet ﷺ got up and glorified Allah as He deserved and then said, "Why do some people impose conditions which are not present in Allah's Book (Laws)? Whoever imposes such a condition as is not in Allah's Laws, then that condition is invalid even if he imposes one hundred conditions, for Allah's conditions are more binding and reliable."  

عَائِشَةُ ؓ دَخَلَ عَلَىَّ رَسُولُ اللَّهِ ﷺ فَذَكَرْتُ لَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ اشْتَرِي وَأَعْتِقِي فَإِنَّ الْوَلاَءَ لِمَنْ أَعْتَقَ ثُمَّ قَامَ النَّبِيُّ ﷺ مِنَ الْعَشِيِّ فَأَثْنَى عَلَى اللَّهِ بِمَا هُوَ أَهْلُهُ ثُمَّ قَالَ مَا بَالُ أُنَاسٍ يَشْتَرِطُونَ شُرُوطًا لَيْسَ فِي كِتَابِ اللَّهِ مَنِ اشْتَرَطَ شَرْطًا لَيْسَ فِي كِتَابِ اللَّهِ فَهْوَ بَاطِلٌ وَإِنِ اشْتَرَطَ مِائَةَ شَرْطٍ شَرْطُ اللَّهِ أَحَقُّ وَأَوْثَقُ  

Aisha said that Barirah came to seek her help in the writing of her emancipation. ʿAisha said to her, "If you wish, I will pay your masters (your price) and the wala' will be for me." When Messenger of Allah ﷺ came, she told him about it. The Prophet ﷺ said to her, "Buy her (i.e. Barirah) and manumit (free) her, for the Wala is for the one who manumits." Then Messenger of Allah ﷺ ascended the pulpit and said, "What about those people who stipulate conditions which are not in Allah's Laws? Whoever stipulates such conditions as are not in Allah's Laws, then those conditions are invalid even if he stipulated a hundred such conditions." (Using translation from Bukhārī 2735)   

أَهْلُهَا إِنْ شِئْتِ أَعْطَيْتِ بَاقِي كِتَابَتِهَا وَيَكُونُ لَنَا الْوَلَاءُ فَلَمَّا أَنْ جَاءَ النَّبِيُّ ﷺ ذَكَرَتْ ذَلِكَ لَهُ فَقَالَ «اشْتَرِيهَا فَأَعْتِقِيهَا فَإِنَّ الْوَلَاءَ لِمَنْ أَعْتَقَ» ثُمَّ صَعِدَ رَسُولُ اللهِ ﷺ الْمِنْبَرَ فَقَالَ «مَا شَأْنُ النَّاسِ يَشْتَرِطُونَ شُرُوطًا لَيْسَ فِي كِتَابِ اللهِ مَنِ اشْتَرَط شَرْطًا لَيْسَ فِي كِتَابِ اللهِ لَم يَجُزْ لَهُ وَإِنِ اشْتَرَطَ مِائَةَ شَرْطٍ»  

[Machine] The Messenger of Allah, ﷺ , stood up and addressed the people, saying: "O Muslims, what is the matter with some people who impose conditions that are not in the Book of Allah? Whoever imposes a condition that is not in the Book of Allah, even if he imposes it a hundred times, it is not more authentic or binding than the conditions set by Allah Himself."  

قَامَ رَسُولُ اللهِ ﷺ فَخَطَبَ النَّاسَ فَقَالَ «يَا مَعْشَرَ الْمُسْلِمِينَ مَا بَالُ أَقْوَامٍ يَشْتَرِطُونَ شُرُوطًا لَيْسَتْ فِي كِتَابِ اللهِ مَنِ اشْتَرَطَ شَرْطًا لَيْسَ فِي كِتَابِ اللهِ وَإنِ اشْتَرَطَ مِائَةَ مَرَّةٍ فَلَيْسَ لَهُ شَرْطُ اللهِ أَحَقُّ وَأَوْثَقُ»  

Return to your people ; if you like that I make payment for the purchase of your freedom on your behalf and I shall have the right to inherit from you, I shall do so. Barirah mentioned it to her people, but they refused and said: If she wants to purchase your freedom for reward from Allah, she may do so, but the right to inherit from her shall be ours. She mentioned it to the Messenger of Allah ﷺ. The Messenger of Allah ﷺ said: Purchase her (freedom) and set her free, for the right of inheritance belongs to only to the one who set a person free. The Messenger of Allah ﷺ then stood up and said: If anyone makes a condition which is not in Allah's Book, he has no right to it, even if he stipulates it hundred times. Allah's condition is more valid and binding. (Using translation from Abū Dāʾūd 3929)   

أَنْ أَقْضِيَ عَنْكِ كِتَابَتَكِ وَيَكُونَ وَلَاؤُكِ لِي فَعَلْتُ فَذَكَرَتْ ذَلِكَ بَرِيرَةُ لِأَهْلِهَا فَأَبَوْا وَقَالُوا إِنْ شَاءَتْ أَنْ تَحْتَسِبَ عَلَيْكِ فَلْتَفْعَلْ وَيَكُونَ لَنَا وَلَاؤُكِ فَذَكَرْتُ ذَلِكَ لِرَسُولِ اللهِ ﷺ فَقَالَ لَهَا رَسُولُ اللهِ ﷺ «ابْتَاعِي فَأَعْتِقِي؛ فَإِنَّمَا الْوَلَاءَ لِمَنْ أَعْتَقَ» ثُمَّ قَامَ رَسُولُ اللهِ ﷺ فَقَالَ «مَا بَالُ أَقْوَامٍ يَشْتَرِطُونَ شُرُوطًا لَيْسَتْ فِي كِتَابِ اللهِ مَنِ اشْتَرَطَ شَرْطًا لَيْسَ فِي كِتَابِ اللهِ فَلَيْسَ لَهُ وَإِنِ شَرَطَ مِائَةَ مَرَّةٍ وَشَرْطُ اللهِ أَحَقُّ وَأَوْثَقُ»
