"Whoever has two wives and is inclined to favor one of them over the other, he will come on the Day of Resurrection with half of his body leaning." (Using translation from Nasāʾī 3942)
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ كَانَتْ لَهُ امْرَأَتَانِ يَمِيلُ لِإِحْدَاهُمَا عَلَى الْأُخْرَى جَاءَ يَوْمَ الْقِيَامَةِ يَجُرُّ أَحَدَ شِقَّيْهِ سَاقِطًا أَوْ مَائِلًا شَكَّ يَزِيدُ
