The Messenger of Allah [SAW] used to tell his wives not to wear jewelry and silk. He said: "If you want the jewelry and silk of Paradise, then do not wear them in this world." (Using translation from Nasāʾī 5136)
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَمْنَعُ أَهْلَهُ الْحِلْيَةَ وَيَقُولُ «إِنْ كُنْتُمْ تُحِبُّونَ حِلْيَةَ الْجَنَّةِ وَحَرِيرَهَا فَلَا تَلْبَسْنَهَا»
