Seeing Malakoot (Unseen World)

One of the Shaykh Rajab Ali Khayyat's (ra) disciples related: 'I asked the late Haj Muqaddas whether the following hadith attributed to the Holy Prophet (s) is correct:

"If it were not that devils are dominant over the hearts of human beings, they would be witnessing the Malakut."

He answered: 'Yes.'

I asked: 'Do you see the Malakut of the heavens and the earth?

'No, but Shaykh Rajab Ali Khayyat [ra] does!' He replied.
