"The Messenger of Allah ﷺ would seek refuge from the jinn and the (evil) eye of humans, until Al-Mu'awwidhatain were revealed. So when they were revealed he used them and left other than them."  

كَانَ رَسُولُ اللَّهِ ﷺ يَتَعَوَّذُ مِنَ الْجَانِّ وَعَيْنِ الإِنْسَانِ حَتَّى نَزَلَتِ الْمُعَوِّذَتَانِ فَلَمَّا نَزَلَتَا أَخَذَ بِهِمَا وَتَرَكَ مَا سِوَاهُمَا
