(i) Humility, sobriety and pondering over the meanings of the dhikr and the du'a.
(ii) Lowering one's voice as much as possible so as not to disturb others but at the same time one must be completely awake. As Allah says: (And remember your Lord by your tongue and within yourself, humbly and with fear without loudness in words in the mornings, and in the afternoons and be not of those who are neglectful).
(iii) Abiding by the sequence of the group if the dhikr is performed collectively. One should not be too fast nor too slow in observing the sequence; but rather keep up with the pace of the group.
(iv) Cleanliness and respectability of clothes and the place of dhikr. By observing these guidelines, one will find happiness in his heart, light in his soul and blessings from Allah.
