we did not send any apostle except with the language of his people so that he might make clear to them. then allah leads astray whomever he wishes and he guides whomsoever he wishes and he is the allmighty the allwise.
وما أرسلنا من رسول إلا بلسان قومه ليبين لهم فيضل الله من يشاء ويهدي من يشاء وهو العزيز الحكيم
