Question: Will the one who reads the Qur.aan – yet does not know its meaning be rewarded?
Response: Yes, he will be rewarded; and this is based upon the generality of his (sal-Allaahu ‘alayhi wa sallam) saying:
«Whoever reads the Qur.aan, then for every letter he will earn ten good deeds…» and he (sal-Allaahu ‘alayhi wa sallam) went on to say:
«…I do not say that Alif – Laam – Meem is a letter, but Alif is a letter, Laam is a letter, and Meem is a letter»
And that is [the case] whether he knows its meaning or not.
And Allaah [alone] has the Complete knowledge [of all affairs].
