Scholars have made a distinction between people capable and incapable of learning Arabic. As long as you are capable, do your best until you can recite Al-Fatihah and the essential utterances of Salah. If you have difficulty learning Arabic, you should at least learn Al-Fatihah, and you can recite the essential utterances of Salah in your own language.
If you have only learned part of Al-Fatihah, you should recite Al-Fatihah as best as you are able, and then glorify Allah, praise Him, magnify Him, and proclaim His Oneness as explained in the previous hadith, so that these words of remembrance make up for whatever parts are left out of Al-Fatihah.
However, if after much effort you still cannot learn Al-Fatihah at all or anything of the Qur’an, you are exempted from the obligation of reciting the Qur’an on account of your inability to learn it. This is based on Allah’s Saying:
“Allah burdens not a soul beyond its capacity”
You should instead recite the five utterances of remembrance prescribed by Prophet Muhammad (peace and blessings be upon him).
