Assalamulaikum, backstory: So in my family when I was young I was sent to Arabic studies but my family had financial problems and problems with the arabic tutor apparently so I didnt learn how to read Arabic, I know about 4 Surah's and was not taught how to pray. I reached puberty at 12, and when I was about 18/19 I started pushing myself to learn how to pray. I learned from the internet, and seeing others, but my arabic pronounciation isn't that good since I memorise transliteration of Surahs (as I cannot read Arabic)
I have missed approx. 8 years of prayer
Does sunnah and nafl prayers still count if you have 8 years of prayers you haven't made up for? How can I make up for the prayers because on rough calculations I have 50,000 prayers to make up.
