It was narrated from Ibn 'Abbas that the Messenger of Allah said:

"A previously married woman has more right to decide about herself (with regard to marriage) than her guardian, and a virgin should be asked for permission with regard to marriage, and her permission is her silence."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا مَالِكٌ، عَنْ عَبْدِ اللَّهِ بْنِ الْفَضْلِ، عَنْ نَافِعِ بْنِ جُبَيْرِ بْنِ مُطْعِمٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " الأَيِّمُ أَحَقُّ بِنَفْسِهَا مِنْ وَلِيِّهَا وَالْبِكْرُ تُسْتَأْذَنُ فِي نَفْسِهَا وَإِذْنُهَا صُمَاتُهَا " .
