"The Messenger of Allah [SAW] forbade giving a false impression."  

إِنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنِ الزُّورِ  

"I saw Mu'awiyah bin Abi Sufyan on the Minbar, holding a ball of hair such as women use. He said: "What is wrong with Muslim women who put such things (on their heads)? I heard the Messenger of Allah [SAW] say: "Any woman who adds hair to her head that is not hers, it is something false, that she is adding to her head."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ أَيُّمَا امْرَأَةٍ زَادَتْ فِي رَأْسِهَا شَعْرًا لَيْسَ مِنْهُ فَإِنَّهُ زُورٌ تَزِيدُ فِيهِ
