Aḥmad Sirhindī, a Naqshbandī reformer of the seventeenth century, held that the experience of oneness reported by mystics is a stage of witnessing, in which the seeker sees only God, not a truth about being: creatures remain distinct from their Creator. His view was set against waḥdat al-wujūd.

Also: Wahdat al-shuhud, unity of witness
