عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ لَيْسَ لِلْوَلِيِّ مَعَ الثَّيِّبِ أَمْرٌ وَالْيَتِيمَةُ تُسْتَأْمَرُ فَصَمْتُهَا إِقْرَارُهَا
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: The guardian has no authority in the matter of a widow’s marriage, and permission should be sought from a virgin girl, and her silence will be considered her consent.
