What is meant by the remembrance of Allah the Exalted?

The questioner : What is meant by the remembrance of Allah (Mighty and Majestic)?

The Shaykh : The remembrance of Allah is divided into two categories: verbal remembrance and heart remembrance. The adhkar (remembrances) that came in the Book and the Sunnah refer to verbal remembrance. Verbal remembrance includes heart remembrance, but heart remembrance, if it is devoid of verbal remembrance, is not considered remembrance; rather, it is merely thinking.
For example, some people read by opening the mushaf and reading it in their minds without moving their tongues. This is not reading and it is not remembrance, so the virtue of the saying of the Prophet (peace and blessings be upon him): is not recorded for them. The one who reads from the mushaf with his eyes is not granted this great reward. This is his sin. The expiation is only in the verses of Allah and in the dominion of Allah in the heavens and the earth, as our Lord (Mighty and Majestic) indicated in His saying: This is verbal and heart remembrance. Then He said: This is heart remembrance. Then He said after His saying: This is heart remembrance. Then He said: This is verbal and heart remembrance. We must therefore be aware of two things: in the prescribed remembrance, both the movement of the tongue and the presence of the heart must be present. If one of them is lacking, it ceases to be remembrance. The Shari'ah remembrance must include both the remembrance of the tongue and the remembrance of the heart. If one of them is lacking, it ceases to be remembrance. Do you understand? There is a person who is remembering Allah, but his heart is distracted and heedless; this remembrance has no value. Another person is remembering Allah in his heart and with his eyes, but he does not move his tongue. This is not remembrance. Therefore, the Shari'ah remembrance is the combination of the remembrance of the tongue and the remembrance of the heart.
