﴿ فَمَن لَّمْ يَجِدْ فَصِيَامُ شَهْرَيْنِ مُتَتَابِعَيْنِ مِن قَبْلِ أَن يَتَمَآسَّا ۖ فَمَن لَّمْ يَسْتَطِعْ فَإِطْعَامُ سِتِّينَ مِسْكِينًۭا ۚ ذَٰلِكَ لِتُؤْمِنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ ۚ وَتِلْكَ حُدُودُ ٱللَّهِ ۗ وَلِلْكَٰفِرِينَ عَذَابٌ أَلِيمٌ ﴾

“However, he who does not have the where­withal shall fast [instead] for two consecutive months before the couple may touch one another again; and he who is unable to do it shall feed sixty needy ones: this, so that you might prove your faith in God and His Apostle. Now these are the bounds set by God; and grievous suffering [in the life to come] awaits all who deny the truth.”

ذَٰلِكَ لِتُؤْمِنُوا بِاللَّـهِ وَرَ‌سُولِهِ وَتِلْكَ حُدُودُ اللَّـهِ وَلِلْكَافِرِ‌ينَ عَذَابٌ أَلِيمٌ (...This is [ laid down ] so that you believe in Allah and His Messenger. And these are the limits set by Allah. And for the disbelievers there is a painful chastisement. 58:4) This part of the verse contains the phrase 'so that you believe'. Belief here implies 'to act upon the sacred laws, ordinances and injunctions or obey the commandments of Allah and His Messenger'. Then the verse says that the laws of expiation are limits set by Allah. It is prohibited to exceed them. It indicates that in matters of marriage, divorce, incestuous comparison and so on, Islam has abolished all traces of pre-Islamic pagan elements of customs and practices, and set down the just and approved code of conduct. Man is required to stick strictly to the parameters of Islam. Those who oppose and deny the Divine limits will be tormented most severely.
