عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ بَرِيرَةَ جَاءَتْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا تَسْتَعِينُهَا فِي كِتَابَتِهَا وَلَمْ تَكُنْ قَضَتْ مِنْ كِتَابَتِهَا شَيْئًا فَقَالَتْ لَهَا عَائِشَةُ رَضِيَ اللَّهُ عَنْهَا ارْجِعِي إِلَى أَهْلِكِ فَإِنْ أَحَبُّوا أَنْ أَقْضِيَ عَنْكِ كِتَابَتَكِ وَيَكُونَ وَلَاؤُكِ لِي فَعَلْتُ فَذَكَرَتْ ذَلِكَ بَرِيرَةُ لِأَهْلِهَا فَأَبَوْا وَقَالُوا إِنْ شَاءَتْ أَنْ تَحْتَسِبَ عَلَيْكِ فَلْتَفْعَلْ وَلْيَكُنْ لَنَا وَلَاؤُكِ فَذَكَرْتُ ذَلِكَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ابْتَاعِي فَأَعْتِقِي فَإِنَّمَا الْوَلَاءُ لِمَنْ أَعْتَقَ قَالَتْ ثُمَّ قَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ مَا بَالُ أُنَاسٍ يَشْتَرِطُونَ شُرُوطًا لَيْسَتْ فِي كِتَابِ اللَّهِ عَزَّ وَجَلَّ مَنِ اشْتَرَطَ شَرْطًا لَيْسَ فِي كِتَابِ اللَّهِ عَزَّ وَجَلَّ فَلَيْسَ لَهُ وَإِنْ شَرَطَ مِائَةَ مَرَّةٍ شَرْطُ اللَّهِ عَزَّ وَجَلَّ أَحَقُّ وَأَوْثَقُ
Narrated from Sayyida Aisha (may Allah be pleased with her), she says: Sayyida Barirah (may Allah be pleased with her) came to me, seeking my help regarding her contract of emancipation, and she had not yet paid anything. I said to her: Go back to your owners; if they agree that I pay your contract amount and your allegiance (wala’) is for me, then I can do so. She went to her owners and told them everything in detail, but they refused and said: If she (Sayyida Aisha, may Allah be pleased with her) wants to pay your amount for the sake of reward, then that is fine, but the allegiance (wala’) will still be for us. When I told this to the Messenger of Allah (peace and blessings be upon him), he said: Aisha! Buy her and set her free; allegiance (wala’) is only the right of the one who sets free. Then the Messenger of Allah (peace and blessings be upon him) stood up and said: What is wrong with people that they start making such conditions which are not in the Book of Allah? Whoever makes a condition that is not in the Book of Allah, it is nothing for him, even if he makes a hundred conditions. The condition of Allah is the most deserving and the strongest.
