A rabbit that a man had roasted was brought to the Prophet ﷺ. When the man presented it to him, he said, "Messenger of Allah, I noticed that it had blood on it."The Messenger of Allah ﷺ left it and did not eat from it. He said to those with him, "Eat, for had I desired it, I would have eaten it."A man was sitting there, and the Messenger of Allah ﷺ said to him, "Come closer and eat with the people."The man replied, "Messenger of Allah, I am fasting."He said, "Why did you not fast the white days?"The man asked, "What are they?"He said, "The thirteenth, the fourteenth, and the fifteenth."
