[Machine] To marry a woman, the only valid marriage in Islam, he must pay her dowry, inherit from her, and be inherited by her. He cannot divorce her for a fixed period of time, as she is his wife. If one of them dies, they do not inherit from each other.  

البيهقي:١٤١٧٥وَأَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ بِشْرَانَ بِبَغْدَادَ أنبأ إِسْمَاعِيلُ الصَّفَّارُ ثنا عَبْدُ الْكَرِيمِ بْنُ الْهَيْثَمِ ثنا أَبُو الْيَمَانِ أَخْبَرَنِي شُعَيْبٌ عَنْ نَافِعٍ قَالَ قَالَ ابْنُ عُمَرَ لَا يَحِلُّ لِرَجُلٍ
