[Machine] The Messenger of Allah ﷺ said: "A woman should not be married without the permission of her guardian (wali). If she is married without her guardian's permission, then her marriage is invalid. If this invalid marriage happens three times, then she is entitled to the dowry (mahr) equal to what she had received from the previous marriages. If they argue about it, then the ruler is the guardian for the one who has no guardian."
ؓ زَوْجِ النَّبِيِّ ﷺ عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ لَا تُنْكَحُ امْرَأَةٌ بِغَيْرِ أَمْرِ وَلِيِّهَا فَإِنْ نَكَحَتْ فَنِكَاحُهَا بَاطِلٌ ثَلَاثَ مَرَّاتٍ فَإِنْ أَصَابَهَا فَلَهَا مَهْرُ مِثْلِهَا بِمَا أَصَابَ مِنْهَا فَإِنِ اشْتَجَرُوا فَالسُّلْطَانُ وَلِيُّ مَنْ لَا وَلِيَّ لَهُ
