أَخْبَرَنَا مُحَمَّدُ بْنُ رَافِعٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَنْبَأَنَا مَعْمَرٌ، عَنْ صَالِحِ بْنِ كَيْسَانَ، عَنْ نَافِعِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ لَيْسَ لِلْوَلِيِّ مَعَ الثَّيِّبِ أَمْرٌ وَالْيَتِيمَةُ تُسْتَأْمَرُ فَصَمْتُهَا إِقْرَارُهَا ‏"‏ ‏.‏

It was narrated from Ibn 'Abbas that the Prophet said: "The guardian has no right (to force) the previously married woman (into a marriage). And an orphan girl should be consulted, and her silence is her approval." Translation Not Available
