The Book of Marriage
16/9. Chapter:
Seeking permission of a previously-married woman in words, and of a virgin by silence
Sahih Muslim
وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، بِهَذَا الإِسْنَادِ وَقَالَ " الثَّيِّبُ أَحَقُّ بِنَفْسِهَا مِنْ وَلِيِّهَا وَالْبِكْرُ يَسْتَأْذِنُهَا أَبُوهَا فِي نَفْسِهَا وَإِذْنُهَا صُمَاتُهَا " . وَرُبَّمَا قَالَ " وَصَمْتُهَا إِقْرَارُهَا " .
Sufyan reported on the basis of the same chain of transmitters (and the words are): A woman who has been previously married (Thayyib) has more right to her person than her guardian; and a virgin's father must ask her consent from her, her consent being her silence, At times he said: Her silence is her affirmation.
