The Prophet ﷺ said: Any woman who is married by two guardians (to two different men) belongs to the first woman who is married by two guardians (to two different men) belongs to the first of them and anything sold by a man to two persons belongs to the first of them. (Using translation from Abū Dāʾūd 2088)
أَنَّ نَبِيَّ اللهِ ﷺ قَالَ «أَيُّمَا امْرَأَةٍ أَنْكَحَهَا وَلِيَّانِ جَمِيعًا فَهِيَ لِلْأَوَّلِ مِنْهُمَا وَأَيُّمَا رَجُلٍ بَاعَ بَيْعًا مِنْ رَجُلَيْنِ جَمِيعًا فَهُوَ لِلْأَوَّلِ مِنْهُمَا»
