He replied: “The Messenger of Allah, peace and blessings be upon him, was continuously saddened, ever deep in thought, and he knew no worldly repose. He was given to long silences and would not speak unless there was a need. He began and ended his words with the Name of Allah, exalted be He. He spoke in succinct, comprehensive phrases; his speech was decisive—neither excessive nor lacking.”⦗20⦘
