as for the excuse for impossibility that it is added to the matter described by the thing since its opposite is impossible for it not everything impossible is like that for the existence of a partner for god is impossible and there is no matter to which impossibility can be added. if they claim that the meaning of the impossibility of a partner is that god almightys isolation and oneness in his essence is necessary and the isolation is added to him then we say it is not necessary for the world exists with him and is not isolated. if they claim that his isolation from a counterpart is necessary and the opposite of the necessary is impossible and it is an addition to him then we say we mean that gods isolation from them is not like his isolation from a counterpart for his isolation from a counterpart is necessary and his isolation from possible creatures is not necessary so we take it upon ourselves to add possibility to him by this trick just as they took it upon themselves to return impossibility to his essence by changing the expression of impossibility to necessity and then by adding the isolation to him with the attribute of necessity.
وأما العذر عن الامتناع بأنه مضاف إلى المادة الموصوفة بالشيء إذ يمتنع عليه ضده، فليس كل محال كذلك فإن وجود شريك لله محال، وليس ثم مادة يضاف إليها الامتناع. فإن زعموا أن معنى استحالة الشريك أن انفراد الله تعالى بذاته وتوحده واجب والانفراد مضاف إليه، فنقول ليس واجب، فإن العالم موجود معه فليس منفردا. فإن زعموا أن انفراده عن النظير واجب ونقيض الواجب ممتنع، وهو إضافة إليه، قلنا نعني أن انفراد الله عنها ليس كانفراده عن النظير، فإن انفراده عن النظير واجب وانفراده عن المخلوقات الممكنة غير واجب، فنتكلف إضافة الإمكان إليه بهذه الحيلة كما تكلفوه في رد الامتناع إلى ذاته بقلب عبارة الامتناع إلى الوجوب ثم بإضافة الانفراد إليه بنعت الوجوب.
