Salim b. Abul Ja'd told of a man of Khuza'a saying,“I wish I had prayed and been at rest.”When the people seemed to disapprove of his saying that, he replied that he had heard God’s Messenger say,“Declare that the time for prayer has come, Bilal, and give us rest by it.”* * This probably means that prayer brings peace of mind. Abu Dawud transmitted it.
