Hazrat Ibn Shihab says that one day I was sitting in the gathering of Hazrat Abu Idris Khaulani, and he was narrating an incident. He said, "Shall I not tell you about the person whose food was the purest among all people?" When the people looked towards him, he said, "The food of Hazrat Yahya bin Zakariya was the purest among all people. He used to eat in solitude because he did not like to share his life with people."
