Falahu's-Sail, it is narrated from Imam Zeynelabidin (a.s): "Whoever reads this prayer, Allah will remove poverty from him and protect him from the evil of all predatory animals." protects:
اَللّهُمَّ أنْتَ الأوَّلُ فَلا شَىْءَ قَبْلَكَ وَ أنْتَ الظّاهِرُ فَلا شَىْءَ فَوْقَكَ وَ أنْتَ الْباطِنُ فَلا شَىْءَ God bless you السَّماواتِ السَّبْعِ وَ رَبَّ الأرَضينَ السَّبْعِ وَ رَبَّ God bless you اَعُوذُ بِكَ مِنْ شَرِّ كُلِّ دآبَّةٍ أنْتَ آخِذٌ بِناصِيَتِها اِنَّكَ عَلَى صِراطٍ مُسْتَقِِيمٍ
Allahumme intellectual first felâ thing qablek, ve intez outward felâ thing fevqak, ve intellectual inward inward felâ dunek, ve intellectual ahiru felâ thing ba'dek, Allâhumme rabbes semâvâtisseb' ve rabbel ara-zînesseb' ve rabbet tovrâti vel incîli vez zebûri vel qur'ânil hakîm, eûzu bike min şerri kulli dâbbeh, ente âhizun binâsiyetihâ, inneke alâ sirâtin mustaqîm.
[O Allah! You are the god before whom there is nothing (before everything); you are the apparent and there is nothing above you; you are the inward and there is nothing below you; you are the last and there is nothing after you; O Lord of the seven heavens, the seven earths, the Torah, the Bible, the Psalms and the ruling Quran! I seek refuge in you from the evil of every living creature. You, You grab (every living creature) by the forelock (you manage it as you wish). Indeed, you are on the right path (you are just, no one will be oppressed near you).]
at-Tehzib from Imam Muhammad Baqir (a.s): "I guarantee that scorpions and other harmful animals will not be able to harm him until the morning for the one who says this sentence before sleeping:
Eûzu bikelimâtillâhit tâmmâtilletî lâ yucavizuhunne berrun ve lâ fâcirun min şerri mâ zere'e ve min şerri mâ bere'e ve min şerri kulli dâbbe, huve âhizun bi nasiyetihâ, inne rabbî alâ sirâtin mustaqîm. I take refuge in your words. So much so that neither the good nor the bad can go beyond it. He grabs (every living creature's) forelock and pulls it (manages it as He wishes). Surely my Lord is on the right path (he is just, no one is oppressed near him).]
