Hawzah News Agency – Imam Sadiq peace be upon him says:

لَيسَتِ البَلاغَةُ بحِدَّةِ اللِّسانِ ولا بِكَثْرةِ الهَذَيانِ، ولكنَّها إصابةُ المَعنى‏ وقَصْدُ الحُجّةِ.

'Eloquence is not exemplified by the sharpness of the tongue, nor through excess babbling; rather it is through capturing the intended meaning and aiming at the proof.'
