In the Protection of Allah-azwj
وَ قَالَ ع مَنْ قَرَأَ آيَةَ الْكُرْسِيِّ فِي دُبُرِ كُلِّ صَلَاةٍ مَكْتُوبَةٍ تُقُبِّلَتْ صَلَاتُهُ وَ يَكُونُ فِي أَمَانِ اللَّهِ وَ بِعِصْمَةِ اللَّهِ
And he-asws said: ‘One who recites Ayat Al-Kursy in the end of every Prescribed Salat, his Salat will be Accepted and he would be in the Security of Allah-azwj and with Protection of Allah-azwj’.[1]
