“For the tongue does not keep quiet at all. It is either a tongue that remembers or a tongue that is frivolous and it has to be one of these two.
It is the (nature of the) soul; if you do not preoccupy it with truth, it will occupy you with falsehood. It is the (nature of the) heart; if you do not accommodate it with love of Allaah, it will dwell with love of creation and this is a certain reality. It is the (nature of the) tongue, if you do not preoccupy it with remembrance, it will most definitely occupy you with frivolity.
Thus, choose for your own self one of the two courses and confer upon it one of the two standings.”
