"O you who have believed, decreed upon you is fasting as it was decreed upon those before you that you may become righteous."
— Surah Al-Baqarah 2:183"I saw people hanging by their hamstrings, with the sides of their mouths torn and pouring blood. I said: Who are these? They said: These are the people who broke their fast before it was time."
— Sahih Ibn Khuzaymah
