that the Messenger of Allah ﷺ said: "The best of you is the best to his wives, and I am the best of you to my wives, and when your companion dies, leave him alone." (Using translation from Tirmidhī 3895)   

قَالَ رَسُولُ اللَّهِ ﷺ «خَيْرُكُمْ خَيْرُكُمْ لِأَهْلِهِ وَإِذَا مَاتَ صَاحِبُكُمْ فَدَعُوهُ»
