their saying that the possibility of existence is not existence. if it is said the possibility of existence is for him from his essence and his existence from something else then how can what he has from his essence and what he has from something else be one?
قولهم إمكان الوجود غير الوجود فإن قيل إمكان الوجود له من ذاته ووجوده من غيره، فكيف يكون ما له من ذاته وما له من غيره واحدا؟
