What is the ruling of Islamic law on making errors when counting banknotes due to the inability to distinguish between denominations, and what is the solution to this problem that may lead to numerous issues at work?

Regarding the confusion of banknotes, the remedy is focus and attention, and seeking help from a worker until one trains. As for frequent dreams, if they occur during sleep, they are not cause for concern. It is recommended to spit dryly to the left three times and seek refuge with Allah from Satan, recite Ayatul Kursi and the remembrances before sleep, sleep with ablution, and recite the end of Surat Al-Baqarah and the Mu'awwidhat (Surahs Al-Falaq and An-Nas), while increasing acts of obedience, remembrance of Allah, recitation of the Quran, and removing evil deeds. If they are daydreams, you should occupy your free time by memorizing the Quran and remembering Allah, and stay away from anything that affects the mind, such as Qat.
