Taqwa is the foundation of all protection. Every act of worship performed with sincerity protects the one who performs it. Reciting Ayat al-Kursi has a specific effect in protecting one if it is recited after every prayer, before sleeping and when entering and leaving the house. The awrad of Shaykh Abu Bakr al-Sakran, Imam al-Nawawi and Shaykh Abu Bakr bin Salim are among the greatest litanies composed by the pious for protection.
