Narrated Aisha:Barirah came (to `Aisha) and said, "I have made a contract of emancipation with my masters for nine Uqiyas (of gold) to be paid in yearly installments. Therefore, I seek your help." `Aisha said, "If your masters agree, I will pay them the sum at once and free you on condition that your Wala' will be for me." Barirah went to her masters but they refused that offer. She (came back) and said, "I presented to them the offer but they refused, unless the Wala' was for them." Allah's Messenger (ﷺ) heard of that and asked me about it, and I told him about it. On that he said, "Buy and manumit her and stipulate that the Wala' should be for you, as Wala' is for the liberator." `Aisha added, "Allah's Messenger (ﷺ) then got up amongst the people, Glorified and Praised Allah, and said, 'Then after: What about some people who impose conditions which are not present in Allah's Laws? So, any condition which is not present in Allah's Laws is invalid even if they were one-hundred conditions. Allah's ordinance is the truth, and Allah's condition is stronger and more solid. Why do some men from you say, O so-and-so! manumit the slave but the Wala will be for me? Verily, the Wala is for the liberator."
حَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ جَاءَتْ بَرِيرَةُ فَقَالَتْ إِنِّي كَاتَبْتُ أَهْلِي عَلَى تِسْعِ أَوَاقٍ، فِي كُلِّ عَامٍ وَقِيَّةٌ، فَأَعِينِينِي. فَقَالَتْ عَائِشَةُ إِنْ أَحَبَّ أَهْلُكِ أَنْ أَعُدَّهَا لَهُمْ عَدَّةً وَاحِدَةً، وَأُعْتِقَكِ فَعَلْتُ، وَيَكُونَ وَلاَؤُكِ لِي. فَذَهَبَتْ إِلَى أَهْلِهَا، فَأَبَوْا ذَلِكَ عَلَيْهَا، فَقَالَتْ إِنِّي قَدْ عَرَضْتُ ذَلِكَ عَلَيْهِمْ، فَأَبَوْا إِلاَّ أَنْ يَكُونَ الْوَلاَءُ لَهُمْ. فَسَمِعَ بِذَلِكَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَسَأَلَنِي فَأَخْبَرْتُهُ، فَقَالَ " خُذِيهَا، فَأَعْتِقِيهَا، وَاشْتَرِطِي لَهُمُ الْوَلاَءَ، فَإِنَّمَا الْوَلاَءُ لِمَنْ أَعْتَقَ ". قَالَتْ عَائِشَةُ فَقَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي النَّاسِ، فَحَمِدَ اللَّهَ، وَأَثْنَى عَلَيْهِ، ثُمَّ قَالَ " أَمَّا بَعْدُ، فَمَا بَالُ رِجَالٍ مِنْكُمْ يَشْتَرِطُونَ شُرُوطًا لَيْسَتْ فِي كِتَابِ اللَّهِ فَأَيُّمَا شَرْطٍ لَيْسَ فِي كِتَابِ اللَّهِ فَهْوَ بَاطِلٌ، وَإِنْ كَانَ مِائَةَ شَرْطٍ، فَقَضَاءُ اللَّهِ أَحَقُّ، وَشَرْطُ اللَّهِ أَوْثَقُ، مَا بَالُ رِجَالٍ مِنْكُمْ يَقُولُ أَحَدُهُمْ أَعْتِقْ يَا فُلاَنُ وَلِيَ الْوَلاَءُ إِنَّمَا الْوَلاَءُ لِمَنْ أَعْتَقَ ".
