allah knew that they would not sympathize communicate or submit except through discipline and that discipline is only through commands and prohibitions and is ineffective with them except through encouragement and intimidation which are in their nature. so he called them through encouragement to his paradise and made it a substitute for what they had abandoned in the face of his obedience and deterred them through intimidation with hell for disobeying him and frightened them with its punishment for abandoning his command. if he the most high had left them and their original nature they would have followed the laws of nature and the usual habits.
فعلم الله أنهم لا يتعاطفون ولا يتواصلون ولا ينقادون إلا بالتأديب، وأن التأديب ليس إلا بالأمر والنهي غير ناجعين فيهم إلا بالترغيب والترهيب الذين في طباعهم. فدعاهم بالترغيب إلى جنته، وجعلها عوضا مما تركوا في جنب طاعته، وزجرهم بالترهيب بالنار عن معصيته، وخوفهم بعقابها على ترك أمره. ولو تركهم جل ثناؤه والطباع الأول جروا على سنن الفطرة، وعادة الشيمة.
