Hi, Don't think they will understand Arabic there. You will need to get a translation done and follow the process described in CIC Instruction Guide for this.

Translation of documents
Any document that is not in English or French must be accompanied by:
•the English or French translation; and
•an affidavit from the person who completed the translation; and
•a certified copy of the original document.
Note: An affidavit is a document on which the translator has sworn, in the presence of a commissioner authorized to administer oaths in the country in which the translator is living, that the contents of their translation are a true translation and representation of the contents of the original document. Translators who are certified members in good standing of one of the provincial or territorial organizations of translators and interpreters of Canada do not need to supply an affidavit.
Important information. Translations by family members are not acceptable.
Then send additional courier hoping to get this added to the original package. Read carefully and follow the below instructions please (also send email with scan copy and ask for confirmation that it has successfully attached):
