That I will not waste the work of a worker among you (Qur’an...
Fourth : From the above discussion it is known that rewards and recompenses are outcomes of praying more for the early reappearance of His Eminence (aj) – whether it be in Persian or Arabic or any other language – from the aspect of the arguments and traditional reports mentioned, like the saying of His Eminence (aj): “And pray more for the reappearance, as in it lies your success” and the saying of Imam Hasan Askari (as) that: “And give him the good sense of praying for His Eminence,” and other traditional reports.
Fifth : It does not make any difference whether the Dua is in poetry or prose just as there is no difference whether the supplicant has composed the text of the Dua himself or someone else has done it, as mentioned in the above discussion.
Sixth : It is allowed for one who is conversant with the language and who knows the value of Dua to compile it in Arabic language, by the proof of precedence of the first [that what has not been prohibited initially, is allowed] and by the argument of generalities and implications of commands for supplicating, without any restriction of language.
That which supports this matter is the statement of the Martyr (r.a.) in the ninth volume of Bihar, in which he relates from Amirul Momineen (as) that he said: The Messenger of Allah (S) said: Indeed, Dua wards off a calamity even if its occurrence is inevitable. Washsha says: I asked Abdullah bin Sinan: Is there a particular Dua for this? He replied: I asked Imam Sadiq (as) and he said: Yes, there is a prescribed Dua for the deprived Shias, for every calamity.
