Wala' (perwalian) adalah hak orang yang memerdekakan, dan syarat yang menyalahinya batal
Imam Ahmad : 24535
حَدَّثَنَا وَكِيعٌ حَدَّثَنَا هِشَامٌ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا كَانَ مِنْ شَرْطٍ لَيْسَ فِي كِتَابِ اللَّهِ فَهُوَ بَاطِلٌ وَإِنْ كَانَ مِائَةَ شَرْطٍ
