Sayyiduna Usamah bin Sharik (may Allah be pleased with him) said: I saw the Bedouins asking the Messenger of Allah (peace and blessings be upon him): Is there any harm upon us in such-and-such? He (peace and blessings be upon him) said to them: "O servants of Allah, Allah has removed harm, except for the one who takes something from his brother's honour; he is the one who has fallen into harm." And he (peace and blessings be upon him) said: "O servants of Allah, seek treatment, for Allah has not placed any disease without placing a cure along with it, except old age." (It was said:) O Messenger of Allah, what is the best thing a servant has been given? He (peace and blessings be upon him) said: "Good character."
