3 things a person can do to stay protected from Shaytaan as mentioned by a senior scholar in this field:
1) Recite Surat al Baqarah as Shaytaan flees from the house it’s recited in as mentioned in Sahih Muslim. In another narration it mentions there is blessings in it, leaving it is sadness and sorceresses cannot come close to it. Another narration mentions, he (Shaytaan) won’t enter the house which it has been recited in for three days!
2. When leaving the house to say the following as it was authenticated by a scholar:
بِسْمِ اللهِ، تَوَكَّلْتُ عَلَى اللهِ، وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ
3. The following is said when a person is scared of a place they are in as mentioned in Sahih Muslim:
أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّاتِ مِنْ شَرِّ مَا خَلَقَ
