"Whoever obeys me, indeed s/he obeys Allah (SWT)." (Bukhari, Muslim)
"Whoever revives my Sunnah, that means s/he loves me, and whoever loves me, s/he is together with me in the heaven." (Tirmidhi)
It's reported that, in the realm of souls some of the souls prostrated Allah while some didn't. Is it true? Were souls subjected to a test before coming into this world and some became rebellious while the others were obedient?
