Treat your spouses equally without showing any kind of partiality or favourtism towards either one.

This hadith warns against favoritism in marriage. It is narrated by Abu Hurairah that the Prophet said that whoever has two wives and is inclined to favor one of them over the other will come on the Day of Resurrection with half of his body leaning. This means that if a husband shows preference for one wife over another, he will be punished for it on Judgment Day. This hadith teaches us about justice and equality in marriage; husbands should treat their wives equally and not show any kind of favoritism or partiality towards either one. It also serves as a reminder to all married couples to be mindful of their actions and words when interacting with each other so they can avoid any kind of injustice or inequality between them.
