Mishkat al-Masabih, 4563

Abu Sa'id al-Khudri told that God’s messenger used to seek refuge in God from jinn and the evil eye in men till the <i>Mu’awwidhatan</i>* came down, after which he made use of them and abandoned everything else. Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying this is a hasan gharib tradition. * Qur’an, 113 & 114.

وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَعَوَّذُ مِنَ الْجَانِّ وَعَيْنِ الْإِنْسَانِ حَتَّى نَزَلَتِ الْمُعَوِّذَتَانِ فَلَمَّا نزلت أَخذ بهما وَترك سِوَاهُمَا. رَوَاهُ التِّرْمِذِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيث حسن غَرِيب
