"The Messenger of Allah [SAW] used to seek refuge from the evil eye of the Jinn and the evil eye of humans. When Al-Mu'awwadhatan were revealed, he started to recite them and stopped reciting anything else."  

كَانَ رَسُولُ اللَّهِ ﷺ يَتَعَوَّذُ مِنْ عَيْنِ الْجَانِّ وَعَيْنِ الإِنْسِ فَلَمَّا نَزَلَتِ الْمُعَوِّذَتَانِ أَخَذَ بِهِمَا وَتَرَكَ مَا سِوَى ذَلِكَ
