(وَعَنْهُ أَيْضًا) قَالَ أَمَرَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ أَقْرَأَ بِالْمُعَوِّذَاتِ دُبُرَ كُلِّ صَلَاةٍ
It is narrated from Sayyiduna Uqbah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) commanded me to recite the Mu'awwidhat, that is, Surah al-Falaq and Surah an-Nas, after every prayer. This is a plural word and by it, three surahs (Ikhlas, Falaq, and Nas) are meant.
