It has been narrated by Hadhrat Ma’qal Ibn Yasaar that Rasulullah (sallellaho alaihe wasallam) said that one who recites thrice in the morning:

أَعُوْذُ بِاللهِ السَّمِيْعِ الْعَلِيْمِ مِنَ الشَّيْطَانِ الرَّجِيْمِ

I seek protection of Allah, the All-Hearing, and All-knowing from shaitaan, the rejected one.

followed by the last three verses of Surah Hasr once, Allah Ta’ala will appoint over him 70,000 angels who will beg for forgiveness

هُوَ اللهﹸالَّذِيْ لآ إِلٰهَ إِلَّا هُوَ عَالِمُ الْغَيْبِ وَالشَّهَادَةِ هُوَ الرَّحْمٰنُ الرَّحِيْمُ○ هُوَ اللهﹸالَّذِي لآ إِلٰهَ إِلَّا هُوَ الْمَلِكُ الْقُدُّوْسُ السَّلَامُ الْمُؤْمِنُ الْمُهَيْمِنُ الْعَزِيْزُ الْجَبَّارُ الْمُتَكَبِّرُ سُبْحَانَ اللهِ عَمَّا يُشْرِكُونَ ○ هُوَ اللهﹸالْخاَلِقُ الْبَارِئُ الْمُصَوِّرُ لَهُ الْأَسْمَاءُ الْحُسْنٰى يُسَبِّحُ لَهُ مَا فِي السَّمٰواتِ وَالْأَرْضِ وَهُوَ الْعَزِيْزُ الْحَكِيْمُ
