Editing Madinatut-Tawhid/GPT4 9

So bear witness, O Salman, that in the treasuries of the knowledge of Allah there are sciences, of which not a single piece of knowledge about any person, nor the unity by which they unify Allah with His servants, nor the highest jewels of singling out is mentioned. But when His mercy preceded all His servants, He accepted from them what He commanded in the time of each messenger and the covenant of each prophet as a favor from Him to all creation. So bear witness that there is no god but Him, whom no one will know, and no soul will reach the beginning of His knowledge, nor will it be attained by all those in the kingdom. If you are in the secrets of the matter, then be observant.

Would that there were sanctified baths and pure hearts for them to fly with this servant in the atmosphere of this knowledge, by which the wings of those who approach have burned. Allah will soon bring forth on earth servants who will not be deterred by the prohibitions of the possessive, and they will fly with the wing of sanctity, walk in the realms of immortality, enter into the pavilion of eternal glory, and not be distracted by affairs in the kingdom or the allurements of the earth from the remembrance of Allah, the Most High, the All-Powerful, the Almighty. When they hear the melodies of the spirit, their eyes will overflow with tears, and they will rejoice with the spirit of Allah and turn towards the beauty of the incomparably holy sanctuary. They will not exchange the signs of Allah for anything, even if they spend all that is in the heavens and the earth. 

Whenever they hear the melodies of Allah, they incline towards the homeland of nearness and sacrifice themselves at every moment. At that time, it is appropriate to begin mentioning what I have intended to before and conclude this praise, which will not be reached by the hearts of the advanced.
