Hadith 182

Narrated Ibn Mas'ud (may Allah be pleased with him): The Messenger of Allah (ﷺ) said: "Allah has set forth a parable of a straight path. On both sides of the path, there are two walls, and within them are open doors with curtains hanging over them. At the head of the path, there is a caller who says: 'Stay straight on the path and do not deviate.' Above that, there is another caller who calls: 'Whenever a servant is about to open one of these doors, he is warned: 'Woe to you! Do not open it, for if you open it, you will enter.'" Then the Messenger of Allah (ﷺ) explained: "The path is Islam, the open doors represent the prohibitions of Allah, the curtains are the limits set by Allah, the caller at the head of the path is the Qur'an, and the caller from above is the admonisher of Allah in the heart of every believer."
