﴿ أُحِلَّ لَكُمْ لَيْلَةَ ٱلصِّيَامِ ٱلرَّفَثُ إِلَىٰ نِسَآئِكُمْ ۚ هُنَّ لِبَاسٌۭ لَّكُمْ وَأَنتُمْ لِبَاسٌۭ لَّهُنَّ ۗ عَلِمَ ٱللَّهُ أَنَّكُمْ كُنتُمْ تَخْتَانُونَ أَنفُسَكُمْ فَتَابَ عَلَيْكُمْ وَعَفَا عَنكُمْ ۖ فَٱلْـَٰٔنَ بَٰشِرُوهُنَّ وَٱبْتَغُوا۟ مَا كَتَبَ ٱللَّهُ لَكُمْ ۚ وَكُلُوا۟ وَٱشْرَبُوا۟ حَتَّىٰ يَتَبَيَّنَ لَكُمُ ٱلْخَيْطُ ٱلْأَبْيَضُ مِنَ ٱلْخَيْطِ ٱلْأَسْوَدِ مِنَ ٱلْفَجْرِ ۖ ثُمَّ أَتِمُّوا۟ ٱلصِّيَامَ إِلَى ٱلَّيْلِ ۚ وَلَا تُبَٰشِرُوهُنَّ وَأَنتُمْ عَٰكِفُونَ فِى ٱلْمَسَٰجِدِ ۗ تِلْكَ حُدُودُ ٱللَّهِ فَلَا تَقْرَبُوهَا ۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ ءَايَٰتِهِۦ لِلنَّاسِ لَعَلَّهُمْ يَتَّقُونَ ﴾

“IT IS lawful for you to go in unto your wives during the night preceding the [day's] fast: they are as a garment for you, and you are as a garment for them. God is aware that you would have deprived yourselves of this right, and so He has turned unto you in His mercy and removed this hardship from you. Now, then, you may lie with them skin to skin, and avail yourselves of that which God has ordained for you, and eat and drink until you can discern the white streak of dawn against the blackness of night, and then resume fasting until nightfall; but do not lie with them skin to skin when you are about to abide in meditation in houses of worship. These are the bounds set by God: do not, then, offend against them - [for] it is thus that God makes clear His messages unto mankind, so that they might remain conscious of Him.”

Fasting by its very nature is an act of patience, and patience involves putting up with all kinds of difficulties in order to carry out God’s commandments. This helps man to attain that state of mind which brings him closer to God. Only those find God who surrender themselves totally to Him, only the words of those reach God whose ‘wavelength’ matches that of God. The command to fast is followed by the command, ‘Do not consume one another’s property by unjust means’ (see 2. 188 ). This shows the essence of fasting. The real aim of fasting is to create such a feeling of subservience that when God commands us to abstain from anything, we must do so forthwith. The lesson fasting gives us is that even if God wants us to stay away from lawful things, we must show no hesitation in obeying His command. Thus one who abstains from lawful things if God wants him to do so, will have no difficulty in abstaining from unlawful things if God so commands.
