Say this when you enter the mosque -
أَعُوْذُ بِاللَّهِ الْعَظِيمِ وَبِوَجْهِهِ الْكَرِيمِ وَسُلْطَانِهِ الْقَدِيمِ مِنَ الشَّيْطَانِ الرَّجِيمِ
Transliteration
A‛oodhu Billaahil ‘Azeem, Wabi Wazhihil Kareem, Wa Sultaanihil Qadeem Minash Shaytaanir rajeem
Translation
I seek refuge in Allah, the Magnificent, and in His noble face, and in his eternal domain, from the accursed Devil.
حَدَّثَنَا إِسْمَاعِيلُ بْنُ بِشْرِ بْنِ مَنْصُورٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، عَنْ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ، عَنْ حَيْوَةَ بْنِ شُرَيْحٍ، قَالَ لَقِيتُ عُقْبَةَ بْنَ مُسْلِمٍ فَقُلْتُ لَهُ بَلَغَنِي أَنَّكَ حَدَّثْتَ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَ إِذَا دَخَلَ الْمَسْجِدَ قَالَ " أَعُوذُ بِاللَّهِ الْعَظِيمِ وَبِوَجْهِهِ الْكَرِيمِ وَسُلْطَانِهِ الْقَدِيمِ مِنَ الشَّيْطَانِ الرَّجِيمِ " . قَالَ أَقَطُّ قُلْتُ نَعَمْ . قَالَ فَإِذَا قَالَ ذَلِكَ قَالَ الشَّيْطَانُ حُفِظَ مِنِّي سَائِرَ الْيَوْمِ .

Haiwah b. Shuraih reported : I met ‘Uqbah b. Muslim and said to him: it has been reported to me that someone has narrated to you from the prophet (ﷺ) that when he entered the mosque, he would say: I seek refuge in Allah, the Magnificent, and in His noble face, and in his eternal domain, from the accursed Devil. He asked : is it so much only? I said: Yes. He said: when anyone says so. The devil says: he is protected from me all the day long. [Sahih (Albani). Abu Dawud: 466]
Keep your heart clean and safe with this dua for protection from shaitan. Every masjid visit becomes full of Barakah and peace from Allah.
Say: My Lord, I ask You to keep me safe from the tricks of the devils, And I ask You, my Lord, so they do not come near me. This safety dua stops shaytan's harm and whispers.
Surat Al-Baqarah keeps shaytan away from your house. Read it often for home and family safety. It makes your place safe and calm.
Strong duas for safety are: My Lord, I ask You to keep me safe from the tricks of the devils, And I ask You, my Lord, so they do not come near me. This keeps bad things far.
Say A'oodhu Billah during prayers or anytime you want safety. Once in the first rak'ah is enough, but you can say it more for protection.
Remember Allah all day, pray on time, and read Quran verses. Stay close to Islam and say safety duas to keep shaytan away.
