CONFIDENTIALITY H 694 "The Prophet, praise and peace be upon him, came across Anas when he was playing with some boys, he greeted them and sent Anas on an errand which caused him (Anas) to be late returning to his mother. When Anas arrived she asked: 'What has detained you?' Anas replied, 'The Prophet, praise and peace be upon him, sent me on an errand.' She asked, 'What was the errand?' Anas replied: "It was secret." So his mother said, 'Do not tell anyone about the secret of the Prophet, praise and peace be upon him.' Anas told Thabit, 'If I was going to tell anyone it would have been you.' R 694 Thabit related that Anas said this.
