Allah, the Almighty, said:

{O reassured soul} [al-Fajr 89:27]

Ṭuma’neenah is a quiescence that is buttressed by valid security,⁴⁸² which is similar in certainty to the witness of the eye. There are two differences between it and sakeenah (tranquility):
The first: sakeenah is an impetus that causes, at times, the abatement of the [intensity of the] awe.⁴⁸³ However, ṭuma’neenah is the quiescence of security in the oasis of comforting intimacy (uns).⁴⁸⁴
The second: sakeenah is a description that may simply be had at times, whereas ṭuma’neenah never separates from its people.
It is of three levels:

The first level is the serenity of the heart in the remembrance of Allah. It is the serenity found by:

1. the fearful in hope


2. the aggravated in (the resignation to) destiny


3. the afflicted in (the expectation of) reward

The second level is the serenity of the soul:

1. in the disclosure⁴⁸⁵ while traveling


2. in the promise while yearning⁴⁸⁶


3. in the union while in tafriqah (dispersion)⁴⁸⁷

The third level:

1. the serenity in the (Divine) gentleness while beholding the (Divine) presence⁴⁸⁸


2. the serenity in (the station of) baqâ’ (subsistence) while in [the state of] union⁴⁸⁹


3. the serenity in the light of pre-eternity while
   in one’s station⁴⁹⁰
   

⁴⁸² Not the fake security that results from heedlessness, wishful thinking, and delusions.
⁴⁸³ The awe that comes with reflection on the attributes of might and rigor.
⁴⁸⁴ The uns that comes in the state of togetherness with the True One, reflecting on His attributes of mercy and beauty and on the Divine essence (dhât).
⁴⁸⁵ Disclosures show the details of the way and the destination, giving assurance to the traveler.
⁴⁸⁶ While yearning for His pleasure, you find comfort in His promise to the good doers.
⁴⁸⁷ Your occupations in the dunyâ cause tafriqah (dispersion, distraction, discomposure), and your togetherness with Allah, during your devotional retreats (or even during your occupation), will provide your spirit with comfort and composure.
⁴⁸⁸ While your heart is beholding the Divine, the realization of His gentleness will keep it at ease.
⁴⁸⁹ Your baqâ (subsistence by Allah, with Him, and for Him) will result from your togetherness with Him and your heart will find stability in that loftiest station.
⁴⁹⁰ The light of pre-eternity removes every darkness and puts all things in perspective, realizing the oneness of the origin.
