What is the ruling on eating when one craves food, not out of hunger, and does consuming sweets and tea between meals contradict the Hadith: "We are a people who do not eat until we are hungry, and when we eat, we do not eat to satiety"? Is this considered extravagance, and what should one do about the obsessive fear of violating the Hadith?

The aforementioned hadith (definition) is weak. There is no harm in eating when one desires, even without hunger, as long as it causes no medical harm. The same applies to consuming sweets, tea, and other similar items, for Allah has permitted good things without extravagance. This is indicated by His Almighty's saying: "Say, 'Who has forbidden the adornment of Allah which He has produced for His servants and the good things from His provision?'" and His saying: "And eat and drink, but be not excessive." Ibn Hajar mentioned that consuming good things does not contradict asceticism. Therefore, there is no harm in consuming food, sweets, and tea, as long as it does not harm one's health and is without extravagance.
