"For those of us who do not have a good understanding of Arabic grammatical rules and can only recite by looking at the text, it is difficult to identify or understand these minor issues, let alone know the solutions. In Surah Al-Falaq, it is written as 'Min Sharri,' but I saw it written as 'Min Sharra' somewhere. Is this a mistake, or is there a specific rule that allows it to be written this way?"
