The right of fasting is that you know it is a veil which God has set up over your tongue, your hearing, your sight, your stomach, and your private part to protect you from the Fire. If you abandon the fast, you will have torn God’s protective covering away from yourself.

وَأَمَّا حَقُّ الصَّوْمِ فَأَنْ تَعْلَمَ أَنَّهُ حِجَابٌ ضَرَبَهُ اللهُ عَلَى لِسَانِكَ وَسَمْعِكَ وبَصَرِكَ وَفَرْجِكَ وبَطْنِكَ لِيَسْتركَ بهِ مِن النَّارِ. فان تركتَ الصومَ خرقتَ ستر الله عليك.
