Did we perform acts of worship in the spiritual realm like prayer, circumambulation etc? What was the reason?

Unknown

The word commonly used by the Syed (as) and many scholars for a realm that existed after the realm of the souls and before the creation of the physical realm is عالم الذر, or Atom World. Its possible is that the human beings who were to be extracted from the progeny of Adam (as) in the physical realm, were extracted there and appeared like atoms.

With regards the question of whether or not we worshipped Allah there: the Syed (as) has addressed this topic in the With the Righteous Servant مع العبد الصالح ج. 1 when he says the following (Translation has been based on the English version made available from The First Mahdi website…

“For example, in the atom world there is no need; because the physical body with which the self would be busy does not exist. As for the fact that the atom world is not prepared for the acts of worship of this world to be performed there, the matter is clear. So now the answer becomes clear, and that is that the test is the same, and it is one and the same in this world and in the atom world and in the Raj’a world (The world of the Return). If Allah decides to test the people a thousand times He would test them with the same test because the purpose of creation is one, and it is to attain ma’rifah (to understand), yes the details of the test differ due to the differences between the worlds. So praying and fasting and Hajj (Pilgrimage), and Zakah (Alms giving) etc, they were all present in the atom world and Allah had tested us with them but according to what was appropriate for that world. So praying (salaat) was one thing and that was that I focus my sight on whatever comes out from Him (swt), and fasting was that I deny myself, and Hajj was that I walk towards Him and circle His door waiting for His command, and Zakah was that I give Him myself and slaughter myself before Him by fighting the I (ego) etc.
