Recite Ayatul Kursi For Protection
Imam Bihaqi (Ra) States:
The one who recites Ayatul Kursi before falling asleep, Allah gives protection to his/her home and his/her Family.
(Marqat Sharah Mishkaat, Mulla Ali Qaderi, vol. 2 pp. 583)
In another Hadith the Jinn and Shaithaan do not come close to the house in which Ayatul Kursi is recited.
(Tirmizi Altargheeb Wal Tarheeb Lilmanzari vol.2 pp.631)
