عَنْ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «خَيْرُكُمْ من تعلم الْقُرْآن وَعلمه» . رَوَاهُ البُخَارِيّ

Abū Mas'ūd reported God’s messenger as saying, “If anyone recites the two verses at the end of sūra al-Baqara at night they will avert harm from him.” *Or will be enough for him. (Bukhārī and Muslim.)
