From the Sidratul Muntaha, Rasulullah (sallallahu ‘alaihi wasallam) ascended even further until he reached such a high place where he was able to hear the sounds made by the pens (recording predestination). The sound produced by the writing of these pens of predestination is referred to as Sareeful-Aqlaam.  

This is the location where the pens of taqdeer were engaged in recording everything that will transpire in the future. The angels were busy writing the divine decisions and religious commandments from the Lowh-e-Mahfooz.

From the place of Sareef-ul-Aqlaam, Rasulullah (sallallahu ‘alaihi wasallam) proceeded and passed through many veils until he arrived in the sacred presence of Allah Ta‘ala.
