One must speak at the right time,
otherwise silence is better than speech:
a word of sympathy with the grief of another, and
a smile at least when another laughs.
One should watch the opportunity for moving a subject in society, and
never abruptly change the subject of conversation, but skillfully blend two subjects with a harmonious link.
Also one should wait patiently while another speaks, and
keep a rein on one's speech when the thought rushes out uncontrollably, in order to keep it in rhythm and under control during its outlet.
One should emphasize the important words with a consideration of strong and weak accent.
It is necessary to choose the right words and mode of expression, to regulate the speed and to know how to keep the rhythm.
Some people begin to speak slowly and gradually increase the speed to such an extent that they are unable to speak coherently.

The above named rules apply to all actions in life.

The Sufi, like a student of music, trains both his voice and ear in the harmony of life. The training of the voice consists in being conscientious about each word spoken, about its tone, rhythm, meaning and the appropriateness for the occasion. For instance the words of consolation should be spoken in a slow rhythm, with a soft voice and sympathetic tone. When speaking words of command a lively rhythm is necessary, and a powerful distinct voice.

The Sufi avoids all unrhythmic actions; he keeps the rhythm of his speech under the control of patience, not speaking a word before the right time, not giving an answer until the question is finished. He considers a contradictory word a discord unless spoken in a debate, and even at such times he tries to resolve it into a consonant chord. A contradictory tendency in man finally develops into a passion, until he contradicts even his own idea if it be propounded by another.
