here are many persons whose Duas are not articulated properly yet they are answered, why is it so? The answer is that God Almighty rewards the supplicant to the extent of his intention and not in accordance with the wrong articulation of Dua.
This claim is supported by Sheikh Koleini in whose book “Kafi” quotes Imam Sadeq and the Holy Prophet of Islam (SAW) as saying:
* * *
23. “If a non-Arab Muslim recites the Holy Quran in his own language, angels will take it up in its correct Arabic version.”
A Hadith on the authority of the Holy Prophet of Islam (SAW) says:
* * *
24. “Our deeds depend on our intention.” or
* * *
25. “A believer’s intention is better than his deed.” or
* * *
26. “God takes Bilal’s “seen” as “sheen” (the Holy prophet’s Muezzin, Bilal could not pronounce sheen (sh) he would say seen (s) instead).
A man came to Imam Ali (A.S.) saying: O Ameer al-Muminin, a person is talking to Bilal but since Bilal can not pronounce the words properly, he is ridiculing Bilal. The Imam (A.S.) said:
* * *
27. “O servant of Allah! the proper articulation of Dua is meant to purify our deeds. Therefore, the beautiful words of one whose deeds is bad, will not avail him. Hence, Bilal’s wrong articulation will not affect his praiseworthy deeds.”
