• To refrain from eating excessively at the time of ifṭār such that the stomach becomes full. He explains that the purpose of fasting is to keep the stomach empty, as a full stomach strengthens the nafs and makes it more difficult to reject unlawful temptations. If, after fasting for the whole day, a person eats more than they normally would, then they have achieved nothing but strengthening their nafs even more than if they had not fasted at all. He further states that it is from the etiquette of fasting not to sleep excessively during the day, so that hunger and thirst are felt and the heart is purified. One should remain in a state of moderated intake even during the night, so that it becomes easier to worship Allāh, as the weakened nafs will be unable to deter the muttaqī from completing the sunan and nawāfil, thereby attaining the pleasure of Allāh.
