never have we sent a messenger but he has addressed his people in their language that he may fully expound his message to them. allah lets go astray whomsoever he wills and guides to the right way whomsoever he wills. 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
