they portray that they are doing a great favour to you by having become muslims say do not think that you have done me a favour by accepting islam in fact allah has bestowed a favour upon you for he guided you to islam if you are truthful.
يمنون عليك أن أسلموا قل لا تمنوا علي إسلامكم بل الله يمن عليكم أن هداكم للإيمان إن كنتم صادقين
