[Machine] "The Prophet ﷺ said, 'The guardian does not have authority over a woman who is of sound mind, and the silence of an orphan girl is considered as her consent.'" Muhammad ibn Ishaq mediated between Salih ibn Kaysan and Nafi' ibn Jubayr, the son of Abdullah ibn Al-Fadl.  

عَنِ النَّبِيِّ ﷺ قَالَ «لَيْسَ لِلْوَلِيِّ مَعَ الثَّيِّبِ أَمْرٌ وَالْيَتِيمَةُ تُسْتَأْمَرُ فَصَمْتُهَا إِقْرَارُهَا» أَدْخَلَ مُحَمَّدُ بْنُ إِسْحَاقَ بَيْنَ صَالِحِ بْنِ كَيْسَانَ وَبَيْنَ نَافِعِ بْنِ جُبَيْرٍ عَبْدَ اللهِ بْنَ الْفَضْلِ  

"A previously married woman has more right (to decide) about herself (with regard to marriage) than her guardian, and an orphan girl should be consulted with regard to marriage, and her permission is her silence." (Using translation from Nasāʾī 3262)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «الْأَيِّمُ أَوْلَى بِأَمْرِهَا وَالْيَتِيمَةُ تُسْتَأْمَرُ فِي نَفْسِهَا وَإِذْنُهَا صُمَاتُهَا»
