Invoking the letters of God's Name without presence of mind is invocation of the tongue; invoking with presence of mind is invocation of the heart; and invoking with an absence of self-awareness because of absorption in the Invoked is the invocation of the Self - this is the hidden invocation!

The realization of 'La ilaha illa Allah' is one of the states of the heart that can be neither expressed by the tongue nor thought out by the mind.

Invoking brings the heart closer to the hereafter and keeps the world away from the heart, even though the world is around it. Invoking warns the heedless heart to abandon its pleasures and deceptions.

If He opens a door for you, thereby making Himself known, pay no heed if your do not measure up to this. For, in truth, He has not opened if for you but out of a desire to make Himself known to you. Do you not know that He is the one who presented the knowledge of Himself to you, whereas you are the one who presented Him with deeds? What a difference between what He brings to you and what you present to Him!

The covenant of your servanthood is that you be a servant to God, not to someone else, and that you know that everything except God is a servant to God, as He Most High has said, "There is none in the heaven and the earth but cometh unto the Compassionate as a servant."

When Allah inspires your tongue to ask, know that He wants to give

The most excellent of those who perform good deeds are those who most often remember God in all situations.
