All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
If you doubt your correct understanding of the meaning of an Islamic text – either from the Quran or the Sunnah – then you should ask the scholars, as Allah says (what means): {So ask the people of the message if you do not know.} [Quran 16:43]
If you understand the meaning of an Islamic text and you do not doubt your understanding of it, then you should act according to it and you will be rewarded, Allah wiling, and you are not considered wrong.
We perceive, dear Sister, that you are afflicted with severe Waswaas (obsessive whispers) regarding the subject of understanding and acting upon Islamic texts. You asked us so many questions, and most of them are on the same subject. In our view, this is only due to being affected with Waswaas, so we recommend that you avoid it and do not pay any attention to it and try to seek knowledge in the proper way, and not by asking too many questions.
Allah knows best.
