Is recitation of the Qur’aan in other than arabic rewarded? For example, reading Surah Kahf in english to gain its benefit?
Imam Ibn Qudamah rahimahullah said:
“Recitation [of the Quran] in other than Arabic is not rewarded/counted nor is its wordings substituted with [other] Arabic wordings whether this person’s recitation is good in Arabic or not good..”
And Shaikhul-Islam Ibn Taymiyyah rahimahullah said:
“As for the recitation of a man to himself [in other than Arabic] then it is not allowed according to the majority of the People of Knowledge. Not in prayer nor outside of prayer”
[Bayaan Talbees al-Jahmiyyah (2/389)]
So based on this, one should recite the Quran only in Arabic and that includes reciting surah al-Kahf on Jummah. It should be recited in Arabic in order to get the rewards as mention in the Hadith about its virtue.
And Allah Knows best
